Outdoor Excursions

We will car caravan the length of Owens Valley from Fossil Falls in the south to the Bishop area in the north. The geologic history of the Owens Valley will be discussed while viewing rocks as young as 10,000 years and as old as 500 million years. On Day 1 we will visit Fossil Falls and see sculpted basalt worn smooth by glacial melt water during the Pleistocene Epoch. We will stop at Owens Lake and discuss its natural and man-made history. We?ll visit the scarp of the 1872 Lone Pine earthquake, an estimated 8 magnitude, one of the largest in California recorded history. Our last stop on Day 1 will be the basalt flows of the Big Pine Volcanic Field, just south of Big Pine. Day 2 will include a look at some 500-million-year-old rocks ? the Poleta Folds and 5,000-year-old trees ? the Bristlecone Pines of the White Mountains. Our last stops will be in Round Valley, just west of Bishop. We will visit the Buttermilk Boulders and the Pine Creek moraine.

Our 2-day excursion will take us to the Owen Gorge, Long Valley Caldera, Convict Lake, Devils Postpile and Rainbow Falls. The Owens River has cut a 450 foot canyon through the Bishop Tuff exposing spectacular patterns within the tuff. At our Long Valley Caldera stop, we will see the depression left from a super volcano eruption 760,000 years ago. Convict Lake sits in a glacier-carved bowl and is bounded by 2 towering peaks, Mt. Morrison and Mt. Laurel. We will discuss ice age features and enjoy one of the most beautiful scenes in the Eastern Sierra. The second day will take us to the San Joaquin River drainage. We will visit and discuss the columnar joiting at Devils Postpile and walk along the river to end our day at Rainbow Falls.

Mammoth Lakes Sierra is a beautiful and exciting region of the 400 mile long Sierra Nevada Mountains.  The excitement comes from the earthquakes and volcanic activity of the area.  The Mammoth Lakes area is one of the most likely places for a volcanic eruption in the lower 48.  We will caravan from Mammoth Lakes to Mono Lake making stops at Mammoth Mountains, Inyo Craters, Devil’s Punchbowl, Obsidian Dome and Panum Crater. Our discussions will include glacial features, the Mono Lake Basin ecosystem and the major plant communities of the Eastern Sierra Nevada.

On our first day we will meet in Livingston, Montana and head east toward Big Timber.  Our first stops will include a discussion of the Mesozoic landscape of Montana, including the dinosaur-bearing Hell Creek Formation.  At Big Timber we will head south, drive up Boulder River Canyon making stops on our way to Natural Bridge Falls.  We will return to McLeod and loop back to Livingston along the West Boulder River.

We will again meet in Livingston on Day 2 and head south driving along the Yellowstone River through Paradise Valley.  Our stops will include features of the Yellowstone Outlet Glacier, Petrified trees of the Tom Miner basin, 3-billion-year-old rocks in Yankee Jim Canyon, Devils Slide, and a boulder field deposited by glacial outburst floods.  We will end the day near Gardiner, MT.

This class will offer the student a look at the eastern part of Yellowstone Country.  We will travel east from Cooke City, down the Clarks Fork of the Yellowstone River along the Chief Joseph Scenic Highway.  This route passes through one of the most scenic areas in Wyoming.  Among the fans of this country was Ernest Hemingway who wrote “Death in the Afternoon” while staying at the L Bar T Ranch on Clarks Fork in the summer of 1930.  The geology here is spectacular.  We will see evidence of the uplift of the Beartooth Plateau and the Heart Mountain Detachment, a landslide the traveled at 500 miles per hour and slid for 50 miles.  We will end the first day in Cody Wyoming with time for dinner and a visit to the Buffalo Bill Cowboy Museum.

Our second day will take us west along the Shoshone River back into Yellowstone Park at the East Entrance Station.  After viewing hoodoos and 2 billion year old rock, we will top Sylvan Pass (8530 feet) and stop at Mary Bay to see evidence of the largest hydrothermal explosion crater in the world.  From Mary Bay we will skirt the north end of Yellowstone Lake and end the day at Fishing Bridge, a small resort within the park.

At 13,770 feet the Grand Teton rises over 7,000 feet above Jackson Hole.  Twelve other peaks of the Teton Range reach over 12,000 feet in elevation.  The Teton Range has moved up along the Teton fault a total of 24,000 feet forming one of the most dramatic ranges in all of the Rockies.  This trip will explore the geologic and glacial history of the Teton Range and Jackson Hole.  We will also discuss the major plant and animal communities.

On line presentations will be followed by a 2 day field trip to Grand Teton National Park.  On the first day stops include Lewis Falls, Signal Mountain, Jenny Lake, Taggart Lake, and Teton Village Aerial Tramway.  On the second day we will travel to the Grand Teton National park Visitor Center at Moose, Blacktail Butte, the Gros Ventre slide and the Snake River Overlook.
