The Yellowstone River Here Has Submerged Rocks Polished, With Scrape Marks, By An Old Glacier

…. “ This morning sunlight is the same as yesterday’s except warmer and softer now that we’re at a lower altitude again.“

Yellowstone River, 14.2 Miles Downriver From Gardiner MT, Which Is 0.9 Miles Upriver From Miner, MT..
I stop to read a sign that describes the Glacier Polished Rocks with Scrape Marks submerged here in the river. My notes say that I see what looks like a glacier terminal moraine 3 miles further downstream.
