Our first day in Yellowstone we decided to visit the Madison River Valley, and the Lower, Middle, and Upper Geyser Basins. Here are a few photos.
You will notice the conspicuous absence of wildlife. Once again on this Rocky Mountain trip elk, bison, bear, and other large mammals have eluded us. It appears that the warm weather has convinced them that it’s not yet time to seek the shelter of the geyser basins. Snow is due tomorrow, so maybe the animals will begin to move.
We did take many photos for art reference. There were many opportunities to study light and shadow. With the weather prediction for tomorrow we may stay in and paint.

I have the strong suspicion that you enjoy your trip. I am just back to Paris and discover your latest posting. In Yellowstone, have you fished any trout? Been yourself eaten up alive by mosquitoes? I shall be waiting eagerly for your next posting.
