This is the only moose that we got to see on our travels. I took the following pictures of Jenny Lake with the Teton Range in the background.
Beginning 100 million years ago, long before today's mountains formed, the collision of tectonic plates along North America's west coast bowed up a vast block of sedimentary rock deposited by ancient seas. Beginning 10 million years ago, movement on the Teton fault generated massive earthquakes causing the mountains to rise while the valley floor dropped. The vertical displacement -- from the sedimentary rocks overlaying the mountaintops to the same layers beneath the valley floor -- approaches 30,000 feet.
While movement on the Teton fault lifted the range, erosion sculpted the landscape. Starting two million years ago, massive glaciers up to 3,500 feet thick periodically flowed south from Yellowstone and filled the valley -- eroding mountains, transporting and depositing huge volumes of rocky glacial debris. As ice sheets filled the valley, alpine glaciers sculpted the jagged Teton skyline. These glaciers carved the peaks and canyons and deposited moraines along the glacier's edge.
Today these moraines dam beautiful lakes, like Jenny Lake, along the base of the Teton Range. The general color scheme of vegetation in the 310,000 acre park hints at this geologic story. Geology, plants, and animals interact dynamically over a large region, or ecosystem.

|Grand Teton, Teton Glacier & Mount Owen|
Glaciers in the Teton Range and across much of the world are retreating in response to changing climate. Since 1967, the Teton Glacier has lost 15% of its surface area. Meltwater helps support rich communities along valley streams, but today's glaciers are producing up to 10% less runoff. If current trends continue, the glaciers of the Teton Range will disappear. Their passing will be one of many transformations this landscape will experience in the face of climate change.

In 1888, J. Pierce Cunningham built this sod-roofed log cabin on his homestead near Spread Creek.
We were able to stop at String Lake and take a walk along the lake. It had a much bigger parking lot than Jenny Lake. There were lots of people at String Lake paddle boarding and kayaking.

|Jackson Lake Dam|
Jackson Lake Dam is a vital link in the development the water and land resources of the Upper Snake River Basin. It is operated by the Bureau of Reclamation, U.S. Dept. of the Interior. It was originally authorized for irrigation, some 1,100,000 acres of the fertile Snake River Valley, and for flood control along the Snake and lower Columbia Rivers. Outdoor recreation and and fish and wildlife conservation have become important project benefits.
