“Van Valkenburg, who worked in Yellowstone in 1985, remembers that on warm summer days some visitors would leave dogs locked in cars, windows cracked. When they returned and opened car doors or windows, the dog would leap out, spot a nearby pool of water and leap right in. But at Yellowstone, those pools are often thermal, with temperatures potentially fatal to animals. So many dogs jumped into one such pool near a hiking trail head, Van Valkenburg said that it was nicknamed ‘Hot Dog Pool.’”
