Grand Teton National Park we had several days when the smoke from burning wildfires obscured the mountains. Normally you can see the mountains from many miles away, but due to the fires the mountain tops faded into the pale blur gray sky. Wildfires are common in the dry summers, and the Park Service and local Fire Departments spend a considerable amount of time monitoring and fighting fires. Each fire that is tracked is named. One of the fires that contributed to the smoke we encountered was the large Berry Fire.
On one of the clearer days, I went back to an overlook I had previously visited to sketch the mountain view across Jenny Lake. Thousands of years ago glaciers moved through Cascade Canyon, pushing rocky debris ahead of their progress. Later, when the glaciers retreated, they left behind a mass of rocky debris which formed a terminal moraine creating Jenny Lake.
I had a lovely time sitting in a shady spot while sketching and talking to several people who were also enjoying the spectacular view.
