Why Climb Mountains

Why Climb Mountains

SMI Founder Kurt Wedberg shares some thoughts on why he’s so passionate about climbing mountains

Why climb mountains? Amid all the hardships COVID brought to our lives, the pandemic of 2020 offered the opportunity for many folks to discover mountaineering.  For the first time people are learning benefits that generations of outdoor lovers have known for decades.  A few of those priceless lessons include invaluable benefits for physical, mental, and spiritual health.  It’s also a great way to make meaningful friendships, and see first hand the importance of protecting our environment. Furthermore, it teaches lessons that can be applied to everyday life.

Mountaineering for physical health

Mountaineering requires a general level of endurance and strength.  The cardiovascular and muscular systems are strengthened over time.  Getting into a regular routine increases energy and stamina.  This in turn adds to the enjoyment and expands opportunities for new and bigger adventures; all while gaining improved health!

Why Climb Mountains: Healthy Diet

There’s nothing like partaking in endurance activities to motivate a good diet.  The human body needs food full of nutrients to function well.  Meal planning is critical.  Unhealthy food will not provide the fuel necessary for long summit days.  Mountaineering creates a great opportunity to explore new foods and develop habits that can be used in everyday life.

Mountaineering for Mental Health

Mental health goes hand in hand with physical health.  As you increase endurance and strength you’re also gaining many benefits for mental health.  Studies show exercising leads to increased energy during the day, better sleep, and sharper memories.  It can have a positive impact on depression, anxiety, can help to relive stress, and boost your overall mood.  It releases endorphins in the brain that energize spirits and promote feelings of calm and well-being.  All of this is happening while you’re enjoying majestic and stunning views in the great outdoors!

Mountaineering for Spiritual Health

As a professional mountain guide for 34 years I’m asked why climb mountains all the time.  There are many reasons such as those mentioned in this article.  But, there are others that are difficult to express in words, but are also some of the most powerful.  There is something deeply spiritual about removing yourself from the daily routine of life and immersing in the beauty of nature.  You provide yourself the opportunity to view life from a different perspective.  Situations that may have appeared as big problems transform into smaller issues amid the majesty of the mountains.  When returning to your normal routine this spiritual cleansing helps make everything else more manageable.

Along with the positive health gains, mountaineering provides several other benefits that enhance your life in remarkably purposeful and worthwhile ways.

Meaningful Lifelong Friendships

For climbers the mountains are an endless supply of pleasure and satisfaction.  Mountaineers retain vitality and an enthusiastic elation for life.  They’re keenly aware their experiences can never be replicated in a man-made setting.  When climbers tie into a rope together something symbolic occurs that runs far deeper than the practicality of immediate safety.  They are trusting each other with their lives and well-being. This creates a bond of friendship that cannot be duplicated in any other way.  Sharing these rich adventures leads to unique lasting friendships.

Why climb mountains? It gives new appreciation for our environment

There is nothing like seeing firsthand a pristine vista to bring a new appreciation for our wild remote lands.  John Muir founded the Sierra Club for this very reason.  He knew if he could offer outings that create opportunities for people to see our wilderness they’ll actively help to preserve it.  Today professional guide services offer expanded resources to experience high and remote places and to learn new skills that help broaden the possibilities available.

Climbing high in remote places offers a profound and unique perspective on the importance of protecting our environment.

Mountaineering teaches patience and persistence while building self esteem

Summit days are long stretching anywhere from 8 – 16 hours.  Mountaineering builds patience and persistence because it requires mental and physical stamina.  When looking at a big mountain it can appear overwhelming thinking about how to climb it.  However, it’s important to divide a mountain into small manageable chunks that can be ticked off one at a time in succession.  As an analogy, when you’re served a large plate of food you don’t eat it in one bite. It is consumed in manageable bite sized mouthfuls.  In the same way, when climbing a mountain, maintaining patience and persistence are essential. Climbs are successful by taking one step at a time and one section at a time.  Accomplishing this task is a huge boost to confidence and self-esteem.

The experiences shared on climbs, such as this well earned summit photo from a winter ascent of Mt. Whitney (14505’/4421m), with like minded people can lead to many life long friendships.

Carstensz Summit Day!

The SMI Team is off at 3:15 AM this morning for the Summit of Carstensz Pyramid. Not raining and the cloud cover at the moment is not a factor. Kurt indicates via Sat Phone that all members are feeling strong and in great spirits after their four day jungle trek.

Will report as soon as I get the latest word.


The Grand Objective

Carstensz Pyramid Expedition June 2013

They are off into the jungles of Indonesia.

After a couple days delay in Jakarta and Bali due to lost baggage, the SMI Team of Fred, James, Carolyn Simmons led by Kurt Wedberg, are now into their third day of trekking the soggy jungles of Indonesia onto their base camp below Carstensz Pyramid. So far the weather has been variable with sessions of continuous rain lending to evening dry spells. Rubber boots are the norm for this portion of  the expedition. Once situated at Base Camp, the Team will change into their Alpine climbing profiles for their summit attempt of one of the worlds Seven Summits.

Kurt is in contact with the SMI Office back here in Bishop via Sat Phone so we will be updating the blog as the expedition progresses with photos and verbal Sat Phone reports. Stay tuned for what will indeed be a momentous Team effort on this very obscure Seven Summit Peak.

Kurt Wedberg Climbs Carstensz Pyramid, Completes the Seven Summits!

September 23, 2012: Summit photo on Carstensz Pyramid (4884m/16,024'). From left to right: Esther Kim, Vanessa O'Brien, Andrea Cordona, and SMI founder Kurt Wedberg.

SMI founder Kurt Wedberg just returned from Indonesia where he guided a climb of Carstensz Pyramid (4484m/16,024’).  This is a write up of the trip as told by Kurt…

On September 15 I boarded a China Airlines flight at LAX bound for Jakarta, Indonesia.  I was meeting three ambitious ladies who intended to climb Carstensz Pyramid located deep in the jungle on the island of Papua.  Carstensz gained notoriety in the international mountaineering community in the 1980s when climbers started including it as one of the coveted “Seven Summits”; the highest mountain on each continent.  Carstensz Pyramid is the highest mountain on the Oceana continent.  Previously this continent was limited to Australia making the highest peak on this continent Mt. Kosciuszko (2228m/7310′).

Carstensz Pyramid (4884m/16,024') located on the island of Papua, Indonesia.

Access to Carstensz Pyramid is one of the biggest hurdles to climbing it.  The island of Papua is still inhabited by several native tribes who see very little contact with people from the outside world.  Two of the biggest tribes are the Dani and Moni.  Since we would be traveling on their land permission needed to be granted for us to walk through their territory.  We also needed their help with hiring porters to carry our gear, fuel, and supplies for 12 days in the jungle.

Our team met in Jakarta on September 16 where we organized our equipment.  We then flew overnight to Timika on the island of Papua.  The weather was hot and humid in this town located a short distance from the coast.  From Timika we took a charter flight to the village of Sugapa.  Here the weather was slightly cooler but the equatorial sun was piercing and bright.  At Sugapa we arranged for Moni tribe members to porter our loads and prepared to start walking.  We would be trekking past the historical boundaries of the Moni territory and it was important that we had them with us.  The trailhead was accessed by riding on the backs of motorcycles along a dirt road for 20+ minutes.

Esther and Vanessa on the backs of motorcycles that will take us to the start of our route. It was about a 15 minutes motorcycle ride over a dirt road.

On September 17 we began our trek.  Over the next 5 ½ days we planned to hike 100km/62 miles to reach Carstensz Pyramid.  On Day 1 we passed by several Moni villages.  It rained hard at times and we quickly learned that two of our most important pieces of equipment we brought were our thick rubber Hunter boots to trample through the mud and an umbrella.  We stayed in the furthest village along this path at 1991m/6532’.  From here the trail became less defined.  On September 18 we traversed a hillside to a large river that we paralleled for most of the 7 hours of walking.  The terrain varied from solid rock to thick mud.  Rain returned after lunch and made our path significantly muddier plus rocks and tree roots became more slippery.  Even with high top boots our pants got caked with mud.  Our camp was pitched at 2276m/7467’ in a small clearing amid thick jungle foliage next to a large roaring river.  Nearby was a creek of clear running water that provided a nice place to wash our pants and boots.  Even after these first two days it became obvious that trekking through the jungle would be hard work.  Every single step requires thought and effort.  Relaxing mentally even for one step is recipe for losing footing on the muddy wet slippery terrain.

Our camp in the jungle on September 18. At each camp we draped a tarp over a wooden frame to give us a dry place to cook and eat meals, plus give us a place to hang out away from the rain.

On September 19 our goal was to get high enough to reach the top end of the thick jungle environment and start entering a large plateau.  Our porters had a camp in mind that offered a good water source and flat terrain for camping.  The path continued to deteriorate throughout the day.  The footing became more slippery, the mud became thicker, and we found ourselves grabbing mossy tree branches to surmount steeper sections of the route.  In the middle of the route we passed a small “village” consisting of one hut and a family.  They were friendly and let us sit on the grass outside their hut and each lunch.  Weather remained warm and humid.  The clothing of choice was long pants and long sleeves for abrasion protection from plants but clothing that would offer breathability to prevent overheating.  I wore a pair of loose fitting and comfortable Patagonia pants and a wool Icebreaker short sleeve shirt.  I was the only team member who chose a short sleeve shirt.  I managed to keep my arms from getting scratched too much but the other three were happy to have worn long sleeves.  I was truly impressed with how well wool garments performed here.  The insulating properties of wool allow it to have a much wider temperature range than any synthetic material I’ve ever used.  In my pack I kept two heavier Icebreaker wool layers in case I needed arm protection and additional warmth.  The day wore on and by late afternoon it became apparent we were running out of water and no camp was in site.  Soon after our water ran out we also started losing our daylight.  We found our pace slowed in the darkness in spite of us donning headlamps.  We kept walking following our porters path finally reaching our intended camp at 3222m/10,570’ in the dark after 10 ½ hours of walking.  Tired and dehydrated we counted it a big blessing we were relieved of dealing with rainy weather while hiking today.

Negotiating the terrain in the jungle.

The team pauses for a photo during a rare sunny morning on the plateau above the jungle. The team hiked for two days over this plateau reaching an elevation as high as 3808m/12,493'.

A typical day of rain on the trail. It rained every day of this trip and with the exception of a couple days it rained during our walk. An umbrella was an invaluable piece of gear for this trip.

We woke on September 20 after a good night of welcomed rest and rehydration.  We’re now half way to our Base Camp for Carstensz Pyramid.  Over the next three days we would gain elevation and the terrain would open up offering us views of the surrounding hillsides.  We hoped this would signal an end to the mud but no such luck!  Instead of mud mixed in with tree roots and slippery rocks we had mud mixed in with wet marshy patches that would deceivingly not support body weight.  A misstep here could mean sinking in past the knee and water entering our boots.  My socks got wet each day regardless because Hunter boots are not breathable.  This is where I found my wool Icebreaker socks to be invaluable.  They would dry out at night and during the day they performed well regardless of how wet they got.  If our socks weren’t getting wet from inside the boots or from a misstep in the marsh they would get wet from the rain that came down heavy at times over the next three days.  Since we were out of the thick foliage of the lower jungle our umbrellas were easier to manage.  Arriving at camp each night with muddy boots and pants and soaked clothing we spent the late afternoons trying our best to clean up and get warm and comfortable in our tents.  We put in camps at 3569m/11,709’ and 3717m/12,194’ before reaching our Base Camp on September 22 at 4330m/14,205’.  Arriving at mid afternoon we had time to organize our climbing gear and prepare for our climb of Carstensz Pyramid in early morning.

September 22 en route to Base Camp. Heavy rain lasted most of the day. Now at higher elevation the temperature dropped from the warm tropical climate to much cooler requiring team members to wear a couple layers of clothing underneath their rain gear. We reached an elevation of 4500m/14,763'.

September 22: Kurt at the high point for the day at 4500m/14,763'. The last thing Kurt purchased for this trip was an umbrella from K-Mart in Bishop. This proved to be his favorite piece of gear!

Base Camp at 4330m/14,205'. Carstensz Pyramid, which was shrouded in clouds all day, is located out of the photo to the right on the other side of the ridgeline.

Our mountain was sitting in a cloud above us with rain soaking the route all day.  Finally by evening time the rain quit and revealed stars through partially cloudy skies.  Our strategy was to leave early, climb efficiently, and hopefully reach the summit by early morning.  We hoped to be on the summit and descending before any precipitation began.  Although it can (and did) rain at any time day or night the odds in the mountain environment usually trend towards less precipitation in the mornings and more in the afternoons.  Just the same we carried our umbrellas for the one hour approach and left them at the base of the route.

The rock on Carstensz Pyramid is hard limestone.  The abrasive nature of it meant it would be hard on our clothing but it also provides a lot of friction making for good hand holds and solid purchase for our feet.  The rock is also not very porous and therefore doesn’t absorb water.  Thus even after so much rain the rock was dry as we started up the route at 3:30am.  The climbing consists of scrambling on terrain anywhere from 3rd class up to low 5th class.  Fixed lines have been placed over the years on various sections and these were in varying degrees of wear.  My job on this climb was to keep these ladies safe, negotiate the most effective route, and coach them on the most efficient techniques to climb.  I checked the integrity of the lines and the anchors and as we got into the rhythm of moving we found the climbing to be very enjoyable.  As daylight approached we found ourselves high up on Carstensz Pyramid approaching the long summit ridge we would traverse.  A few 5th class moves led us to the ridge where we turned left and moved to the most exciting part of the route; a Tyrolean Traverse approximately 30m/98’ long over an airy and exposed spot on the ridge.  The challenge of a Tyrolean Traverse revolves around more mental aspects than physical.  They are usually wildly exposed (hence the need for employing this technique) and intimidating to trust at first but once you start on them it is just a matter of moving across the lines and before you know it you’re on the other side.  I rigged everybody with two safety backup systems and we clipped into five different ropes offering plenty of redundancy and piece of mind.  The remoteness of where we were was not lost on any of us!!

One by one we made it across the Tyrolean Traverse then continued traversing the ridge line.  A couple more impasses were encountered that required stretching across smaller expanses but with good backups and carefully placed hands and feet these posed little problems for the ladies.  The terrain then got easier for the last few minutes leading to the summit.  Vanessa and I found ourselves slightly ahead of the rest.  I surmounted a small notch and looked up 40’ above me and realized that was the summit.  I turned to Vanessa and told her to scramble on past me to the summit and she could be the first to stand on top and I’d get some pictures of her.  She obliged and made the final steps towards the 5th of her Seven Summits!  Shortly afterwards the others joined us on the summit.  We were blessed with intermittent clouds and clear skies offering an occasional view, pleasant temperatures, and no precipitation.  We exchanged summit photos and hugs and made a couple calls on our satellite phones before it was time to descend.

Retracing our steps we made it across the summit ridge and started down as light snow began to fall.  It was wet and melted upon touching the rock.  As we descended further the rock got increasingly wet until small streams were flowing down crack systems all around us.  Our gloved hands got soaked but each step brought us closer to the bottom.  Many rappels and short step downs brought us to the base of the route where our trusty umbrellas awaited us.  As the rain picked up in intensity we hiked back to our camp.  We had snuck in a successful ascent of Carstensz Pyramid and we were happy for that.  It would be another four days of trekking through mud and rain retracing our route back to Sugapa.  We managed that and in the process completed an amazing adventure on a remote and distant island in an exotic land with an experience I’m sure the team will remember for the rest of our lives!

On a personal note this was a truly rewarding experience for me.  As a professional mountain guide at SMI our goal is to keep our clients safe and help them achieve their intended goals.  Along the way we continue to make many new and dear friends.  All those missions were accomplished here.  It also completed my own Seven Summits journey.  It began 20 years ago in July of 1992 when I was a young assistant guide on my first expedition to Mt. McKinley (20,320’/6193m), the highest mountain on the North American continent.  SMI is now positioned to guide climbs on all seven continents.  I’ll share more on the journey to the Seven Summits soon.

I want to extend a big thank you to Andrea, Esther, and Vanessa for sharing such an incredible adventure on Carstensz Pyramid.  I also want to thank my family and dear friends who have been so supportive of me throughout my guiding career.  Finally, a special thank you to all of our clients who we continue to share so many incredibly memorable experiences with.  We look forward to seeing you back and to all the new people we will meet along the way.  We already have many trips lined up for the next coming year and we hope to see many of you on one soon!

Kurt Wedberg and Team summit Carstenz Pyramid!

Minutes ago, a celebratory satellite phone call from the summit delivered the good news that Kurt and Team have successfully climbed Puncack Jaya or Carstensz Pyramid (4884m/16023′), the highest point of the Australasia/Oceania region.

The Climbing Team consists of: Vanessa O’Brien of Boston, MA; Esther Kim of Washington DC; Andrea Cardona of Guatemala; and SMI Guide Kurt Wedberg.

This summit completes the last remaining mountaineering objective on the 7 Summits List for Kurt Wedberg. Although Kurt has climbed the other 6 objectives numerous times during his guiding career, until now Oceana remained a distant goal.

Additionally, this summit signifies the completion of the last remaining objective on the Adventure Grand Slam List for Andrea Cardona. The Adventure Grand Slam List consists of climbing the highest peak on each continent (Denali, Aconcagua, Elbrus, Kilimanjaro, Vinson Massif, Carstensz Pyramid, Everest) and skiing to both the North and South Poles. Ms. Cardona is the first woman from Central America to complete the Adventure Grand Slam.

The Team spent the past 5 days trekking through difficult and technical jungle terrain to reach the base of Puncack Jaya. Now, they will return to camp, rest, and resume their descent through the jungle to the trailhead.

Pictures and updates to follow.
