Next Best Thing to a Time Machine

I’ve never gotten to go in a time machine but until they invent one repeat photography is about as close as I’ll get.

The process starts slowly:  mining the internet, talking to museum archivists, getting hundreds of old photographs with vague descriptions of locations from scientists, leafing through beautiful old books that are worth more than my camera, and ending up with thousands of historic photographs, sketches, and maps on my computer.Lago Dickson Threepeat

Days are spent pouring over maps and working in Google Earth to try to align mountains, glaciers, and ridges, figuring out the most likely area the photo was taken from and how to get there.  From this point it’s time to go to the nearest town, print out the black and white images on paper, load up my backpack with tent, stove, food, and camera gear and go into the mountains.  Some photos can be gotten on an afternoon run, others require multiple days of hiking to get to.

Then the psychology starts.  To find the precise location of  a photograph I find that I need to get into the mind of the photographer I am repeating.  Through repeating many photos I start to learn where different photographers liked standing and what subjects interested them. Alberto de Agostini, a mountaineer at heart, liked shooting from high ridges with grand views.  G.K. Gilbert, a photographer for the U.S. Geological Survey, really liked unique rocks and landscapes.  When I look with this knowledge I can almost intuitively know where they might have stood.Rio_Blanco_Perspectives_sm

Finally it clicks.  Walking along a ridge, seeing two boulders and thinking “Yep.  That is exactly where de Agostini stood.”  Seeing a rock outcrop and thinking, “If I were G.K. Gilbert, that is where I would have taken this photo from.”  And it all comes together.  Get the print out of my pocket, hold it up, and I have a window into the past.

Sometimes the changes are obvious, sometimes subtle, but standing in the same location and being able to see how it looked 50, 80, 100, years ago is an incredible experience.  The next best thing to a time machine: a time window.

Storm over the Rio Baker

Yes, our project is focused on the changes happening in glaciers and alpine ecosystems due to global climate change.  This is the core of what we do, but the reason why most people really care about this is the effects it has on populations.  As our climate changes it will cause dramatic and unpredictable hydrological, social, and ecological changes.  The Rio Baker in the Aysen region of Chile is a focal point for all of these issues. 

The Baker River, the largest river in Chile by volume, flows out of Lago General Carrera.  Fed by glacial melt coming off the Northern Patagonia Ice Field, the second largest ice mass outside of the polar regions, it winds down through lakes and valleys before flowing into the ocean in the town of Tortel.  The controversy surrounds a project to build five hydroelectric dams by the multinational power company hidroAysen on this river, and a subsequent 1,200 miles of high-voltage power lines necessary to distribute the power up to Santiago, Chile.

In this process, we are trying to not take the role of advocates against the dams.  We are hoping to understand this controversy better and be able to share the realities of what this means for the river ecosystem and for the communities involved in this.  To see more photos visit our gallery on Facebook.From talking to people in the area there is a strong division between the people who support that construction of the dams and those who are opposed.  Because the Chilean economy and education systems are highly privatized, many families have trouble affording education for their children or being able to make a living in these rural areas.  When hidroAyisen offers them $400,000 US or more to buy their land to put a power line across it, few people can afford not to take that offer.  At the same time many people see the potential to work building the dams, roads, power lines, and other infrastructure that will accompany this project and see it as a much needed boost to the local economy.  To continue growing its economy, particularly the highly lucrative copper mining in the north, Chile believes it will need to double it’s energy capacity in the next 15 years.  The hidroAysen project would supply 35% of the current total energy capacity of Chile, and would help reduce the dependence on neighboring Argenitna for natural gas imports.

The people who oppose it say it will destroy the things that make this remote area of Patagonia special and worth living in or visiting.  Because the hydroelectric companies own a significant portion of the total water rights to the Baker River, many farmers will no longer be allowed to irrigate their land if hydroAysen actually claims their water rights.  Furthermore, if they are able to secure the right of way for the 1,200 miles of power lines, the rights to cut the trees and the mineral rights underneath will be allocated to other companies to develop creating one of the largest single clear-cuts in the world.  For the local guides who run rafting trips on this spectacular section of the Baker River, they will have to switch to kayaking on a lake as the upper Baker River dam site will inundate these popular class IV and V rapids.

If this wasn’t enough, the biggest problem is that hydroAysen has not studied the volatility of the upstream glaciers at all.  The Colonia Glacier flows off the Northern Patagonia Ice Field and blocks the flow of a small river.  This creates a natural dam of ice.  When the lake fills up and builds up enough pressure it breaks through the ice holding it back releasing a flood of water down towards the Baker River.  As the Colonia Glacier retreats due to global warming these floods, called Glacier Lake Outburst Floods or GLOF’s, are only expected to get bigger.  Not only would these contribute to filling the downstream reservoirs with sediments very rapidly, if one of these GLOF’s caused a failure of a dam on the Baker River the flood would completely wipe out many homes, including the entire town of Tortel.

As it currently stands, the construction of these dams has been approved by the Chilean government, but are being held up by a case in the supreme court.  A decision is expected on this in the next few months.  What does the future hold for these dams?  No one really seems to have any idea what the ultimate decision will be, but we will continue talking to people and learning more about this.  If a decision is made we can only hope it will be well informed.

First Views of the Andino

Our first experience in the Andino verdad has been an incredible trip up Mount Tronador. As with any of our repeat photography trips we started with a stack of photos printed in black and white and ended up with a deeper understanding of a place.

Cierro Tronador is a large volcano hidden behind the mountains near Bariloche, Argentina.  On our first day on the mountain we climbed above Refugio Otto Meiling toward a beautiful ridge called Lamotte. A short hike obtains this ridge giving the spectator wonderful views of two of Tronador’s three summits. From this vantage it is easy to appreciate the former scale of these incredible glaciers that still pour off this volcanoes flanks. Here, we repeated two historic photos. After a short jaunt to a nearby summit to preview our next two adventures, we descended back to the refugio for a great New Years celebration with friends.

On our second day, we climbed Cierro Constitucion. Despite the bushwhacking through lenga bush and tabanos, or horseflies, we were able to summit and take one of our best historic repeat photos to date. Alberto M. de Agostini, in some ways the Ansel Adams of the Andes, took this photo of Tronador´s Frias Glacier from the summit of Constitucion in 1949.  These photos show the most startling changes we’ve witnessed so far.  Our repeat photo reveals an incredible amount of retreat and thinning. Where there were once huge icefalls, there are now rivers, lakes, and breathtaking waterfalls.

Our most difficult decision was to forgo taking our oldest photos. We decided to not climb to Cierro Interncional where these photos were taken from because the temperatures were unusually warm at night and the glacier surface was not freezing. This meant that the loose volcanic rocks were free to crumble off of the summits to the glacier paths below. Instead we chose to climb Pico Argentino, since it had far less rock fall danger. We were living our dreams, celebrating the sunrise as we welcomed the spirit of adventure and gave our thoughts to Travis Lizotte, whose life was taken very near our route.

Phase two is now complete.  Next, we are setting out for Chile, where a whole new adventure awaits:  to better understand and articulate the deep and intricate relationships between glaciers, people, and dams.

Tronador

Cierro Tronador is the heart of our Andes adventure.  Our first  steps into the Patagonian wilderness will be toward the mountain that took the life of our friend and fellow Outward Bound instructor Travis Lizotte.  We dedicate this next portion to celebrate his life and spirit.  In his life he opened his heart to so many people, showing and creating the kindness possible in humanity.  He left a legacy that guides how we may trod our own path giving, and in turn, receiving.

We celebrate Travis and heed the insight of our Canadian friend and experienced guide, Lorenzo.  Lorenzo told us how many of his clients came to the mountains expecting suffering, so they suffered.  On Aconcagua and in the Himalayas, Lorenzo observed  that people who approached a mountain with humility and compassion experienced less of a battle and more of a salutation.  Travis approached life with similar compassion and we believe it is no coincidence that he lived a life rich in happiness and community.

We  hope to approach Tronador with the  same open heart and compassion that Travis lived by.  We celebrate Travis’ life as we  have and will celebrate the life of Matthew Baxter III. These two inspirational men guide  our own interpersonal connections with people we are close to and they inspire us to generate strong bonds among the people outside our communities.
