such an inspirational place. >> this is our story and every part of it needs to be told. we have to take advantage of this or we're going to lose this resource. we kind of love it to death. >> the american's job is to make sure this place is in excellent shape for future generations. . >> owe semitea. hello everybody thank you for joining us here in joe semitea. we are marking the 125th anniversary of the national park. a natural wonder that draws millions of visitors every single year. and that has presented
5:01 pm
monumental challenges for over a century. >> i think about the people that saw this for the very first time. >> it is one of the most beloved places on earth. >> it's one of the most iconic spots on the planet. >> to the soaring granite walls of the lower valley. this is a landscape that defies enspripgs. >> now that we've seen it we are off struck with this. >> but from the moment tourists began to come to yoe semitea and fire was literally shoved over cliffs for a light show better suited for a theme park. >> as the fire burns low. >> reporter: the passing years have brought fires, rock slides, flooding, protests, crowds and traffic. >> people have been telling us for years that they want that
5:02 pm
changed. >> reporter: after 125 years this is a park at a cross roads. so tonight we'll show you how a new generation of park leaders are finding new ways to preserve this land improve your experience as a visitor and shape the park's future. >> again , we've made some mistakes but we're really trying to get it right for the next 100 years. >> reporter: the biggest challenge for facing is all of us. the millions of people who cruise through this park every year. crowd control in yoe semitea has always been a work in progress. >> we have spectacular falls. but the worst of the worst is traffic, crowding, all of those kinds of things. >> reporter: and managing those crowds have has been a challenge for
5:03 pm
decades. >> for people to spend 45 minutes to an hour and a half or bitting the park trying to find parking. >> the park starting rolling out free shuttle buses. >> exactly for the time of the shuttle buses it was much worse. >> reporter: the long-term goal here is a change of culture. getting people out of their cars and onto bikes or this growing system of board walks built to protect the valley meadows. >> not only is it going to lessen the impact on the park but it's going to provide a better experience for people. we want people to come here and find that connection to the park. >> reporter: the other challenge is parking. >> people could come and camp in owe semitea and find out almost any place they wanted and set up a tent. >> reporter: and if you want to spend a few nights on the john muir trail you'll need a
5:04 pm
wilderness permit. but this is a kind of congestion by design ensuring that the park isn't overused. . >> getting us back to managing the park and managing it as a natural system. . >> reporter: which brings us to wild life. when the number of bear incidents exploded the park shifted the responsibility to visitors handing out citations to those who don't secure their food. >> our bear incidents have gone from almost 2000 incidents to about 60. >> reporter: so crowd controlling in owe semitea is an endless balancing act. >> we don't claim to be perfect but we claim to be learning. learning from a lot of experiences. >> reporter: of course owe semitea's story doesn't begin with tourists and vacationers. the mooe walk lived here for generations and there's evidence of habitation in owe semitea up to 5,000 even 6,000 years ago
5:05 pm
and beyond. the gold rush changed everything. sight seers started to arrive and then the man who would show owe semitea to the world. >> john muir was originally from sot land. he was a botanist. -- scotland. he was a botanist. he was passionate about understanding it. he was known for his tenacity and exploring. but the owe semitea that muir explored is changing dramatically. as wilson walker shows us it's melting right before our very eyes. >> we have this walk that is a great intersection of natural landscape and human history. . >> reporter: once a year naturalist pete divine leads a small group of people. >> the group came down this
5:06 pm
valley and the people went up this valley to the high peaks to understand the source. >> up this valley forged by ice to an understanding of what shapes the land we now call owe semitea. >> we walk literally in the very footsteps of john muir, gay land clark, all these great names that came before us and in particular the paths of the glaciers. but the remains of those glaciers are tucked away in the highest points of the park and making your way across this vast must ray of rocks and bolders. but eventually you reach the ice. >> it does take work. this is not something most visitors at owe semitea will get close to. >> if you live in san francisco it's also the very start of your drinking water and it was on these very peaks where john muir
5:07 pm
drove stakes into this ice and 46 days he shattered conventional wisdom and reimagined the historical landscape. >> it was actually a living glacier flowing down the mountain. >> reporter: those pictures tell a dramatic story. >> the glacier is 5% or 10% the volume that it was when john muir was here. >> reporter: a dramatic example of a changing climate. >> the glaciers themselves don't say that people are doing this but it does tell us the climate is changing. >> reporter: changing so quickly that all of this could be gone within a generation. >> it's going to be sad when this is gone.
5:08 pm
>> reporter: ice that coded the land's history for us. at least for a little while there's ice you can still put your hands on. . >> here's a treasure from another time still persisting at the top of the mountain. >> reporter: from vanishing ice in owe semitea attic to the drought floor. the landscape is always changing. just like our understanding of how best to manage this land and as julia good rich shows us tackling that challenge is playing with fire. >> the last fire we had in this burn area was 1990. some of this has never burned. >> reporter: it took four years of planning and absolutely perfect conditions. but crews just burned more than 100 acres of the owe semitea valley floor. >> we accomplished a lot when you look at the landscape compared to the other side of the trail here. >> reporter: we sent 150 years trying to prevent any and all
5:09 pm
fires. >> since we've put the fire out for so long the fuel loading's grown. >> reporter: and fire is very much part of this land's history. >> there's strong evidence that the native americans were managing this landscape before we got here through the use of fire. >> reporter: and once we started putting fires out problems piled up like stacks of kindling. >> look at all this stacked we burned off. >> reporter: there's more fuel, more trees and less diversity. >> way too many mix confer pines in relation to the oak trees. >> reporter: more people. >> all these things come together to make it very, very challenging to put back on the ground. >> reporter: and it's not just a problem in the often crowded valley. think back to this summer's fire near toeg ga pass. >> it's more likely to run into a community than it was 50 years ago. >> reporter: so owe semitea bem
5:10 pm
one of the first national parks to actually embrace fire and hopefully with more controlled burns like this one we can prevent a truly catastrophic fire in the heart of owe semitea. >> we really don't have any other tool in your tool box to affect landscape scale change than fire and fire management. >> so what does the park's future hold? 10, 20, 50 years from now? we'll give you a look at the long-ranged plans including work underway to some of the most famous trees on earth. 4 million people could leave a lot of litter. how a military style mobilize sdaegs manages to pick it all up. and for daredevils around the world why these granite walls are still some of the best climbing areas,,
