Tuesday, 1 October 2019 - The day began before sunrise with a guided wildlife excursion near Yellowstone Lake, where we watched dawn at Fishing Bridge, spotted elk, a doe, swans, a bald eagle, bison, and a distant grizzly feeding on an elk carcass. After scenic stops at Sylvan Lake and the Yellowstone River, we revisited the Lower Falls of the Yellowstone before spending the afternoon and evening walking the Upper Geyser Basin, enjoying eruptions from Old Faithful, Spa, Daisy, and Riverside geysers, and admiring colorful hot springs like Morning Glory Pool.
