Glaciers and Climate
They are still present in Alaska (covering 3% of the land there), WA (800 glaciers), MT, CA, OR, CO, and WY.
They don't occur just in polar areas: Mexico has 3 (above 5000 m elevation); Mt. Kilimanjaro is on the equator (above 4400 m); obviously, areas at elevation can have glaciers. Generally speaking, the temperature declines 3-5 degrees C for every 1000 ft gain in elevation.
There are plenty of reminders (evidences) of glaciation:
