Day 77 - Yellowstone Mammoth Hot Springs and Norris Geysers

The famous Travertine Terraces of Mammoth Hot Springs riminded me of Rome since Rome built so many structures with marble travertine stone; but this travertine was brought alive literally by thermophiles- heat loving bacteria. 

These bacteria give the terraces and hot springs and water runoff kaleidoscopes of color ranging from brown to red to orange to yellow to blue depending on the water temperature. We took a ranger guided walk at the upper terraces and were given the full explanation of the geology and biology of this area of Yellowstone. The natural wonders of Yellowstone are powered by underground heat built up due to the colliding tectonic plates underfoot and due to Rhyolite heated rock and underground water reservoirs and volcanoes!!  In fact, the center of Yellowstone is a massive caldera forming supervolcano which last erupted 640,000 years ago. Yellowstone is truly one of a kind-- a remnant of a volcanic age, with a feel of another planet mixed with beautiful natural landscapes and wildlife, and the first of a great movement-- natural parks reserved from commercial exploit and set aside for the enjoyment and inspiration of the people of the world. I love Yellowstone. 



But Mammoth Hot Springs is only one part of a massive park.  After the hour and a half tour we drove south toward Old Faithful but first we stopped at Norris Geyser Basin. The third largest Geyser Basin at Yellowstone, Norris is most famous for Steamboat Geyser, the highest active geyser in the world at up to 385 feet. Except it erupts every 5 hours to 50 years, with the last known eruption happening in 2010. Not having 5 years to sit and watch, we lingered for ten minutes watching minor twenty foot eruptions. We did walk through the Porcelain Basin, named for dozens of beautifully vibrant hot springs nestled closely together. 



Our final destination for the day was the Old Faithful Inn, a historical log-built hotel directly next to Old Faithful geyser. The lobby was a 100 feet tall V-shaped room built entirely by gorgeous deep brown logs. We enjoyed some drinks, a great dinner and a wonderful Old Faithful geyser show to top off a fun night, the highlight of which was my hitting Steve on the top of the head with a snowball-- thus winning my first Wyoming snowball fight.

Day 96 - Banff Cirque Peak

OMG Canada.  Today was my favorite day. The climb to Cirque Peak started with a lovely hike to Helen Lake, climbing quickly at the start but then gently roaming on the backside of the valley, above tree line and with views south to infinity. I made it quickly to the lake then continued on the trail to Dolomite Pass, scrambling on top of the ridge beyond Helen Lake.  My destination : Once on top of the ridge (above my head), I hiked around another lake and up the sandy right side of Cirque Peak, following the route picture from the scramble guide. I eventually made it to a snowbank at the crest of the upper ridge.  I figured walking below the snowbank to the nose would be safer for me with little snow experience, but I saw old steps cut up the near-vertical snowbank and I decided to go for it.  Kicking steps with my right then left foot then propelling my hiking poles right then left deep in the snow above, I inched my way up a snow wall, keeping three solid contact p...

Day 62 - Colorado National Monument

Established as a national monument early in 1911, Colorado NM is known for its high canyon "rim road" and sandstone spires of Monument Canyon.  The canyons of west Colorado are pretty--as they have more green trees and shrubs than the more famous Utah canyons. This gives them a more alive feeling, although the sandstone spires were formed many thousands of years ago by erosion.  Rim Rock road curves up the the top of the canyon cliff, goes through several round tunnels and is lined with scenic viewpoints. The best views were in he Monument Canyon section, and included in sequence, the Coke Ovens, The Kissing Couple (behind my head), and the most famous of all: Independence Monument, the tall spire in pic 3 and viewed from the side in pic 4.  The original promoter and caretaker of the park, John Otto, was the first person to climb Independence Monument and now it's a climbing right of passage. Every July 4 climbers ascend and mount an American flag at the summit. Fun! ...

Day 99 - Mount Robson

The weather was perfect, 80 sunny and clear with a cool breeze for my attempted  40km, 24 mile round trip hike to Berg Lake at Mount Robson Park.  At 7km, I reached the reflective Lake Kinney. The trail was flat and easy up to here and I made quick time.  At 11km I arrived at the Valley of A Thousand Falls, a colorful glacier valley with beautiful waterfalls falling from all corners. The river flowing in form the left was white while the one from the right was blue--interesting.  At 14km White Falls came into view, first of three major falls. This fall cascaded from down the dark rocks and seemed like artwork to me.  At 17km I experienced the most famous waterfall called Emporer Falls, named for its placement below the steep, nearly unclimable  Emporer Face of Mount Robson.  I scrambled below the fall toward small drops of water to rinse off and was promptly drenched by a wind gust.  At 18km I started up the valley toward Berg Lake to breathtaking...
