Here is yet another April, 1971 menu whose interior is identical to the menus of the last few days. This one features on its cover Bear Lake and Longs Peak in Rocky Mountain National Park, which was created in 1915, four years before Grand Canyon.

The trail circling Bear Lake, which is north of Longs Peak (see below), is considered the most visited trail in Rocky Mountain Park, so it is no surprise that there are many photos of the same location on line. While the Union Pacific photographer did a good job of mirroring the peak in the lake, the menu photo was taken at mid-day, while some of the best on-line photos are at sunrise.
