The distinctive stone-and-log architecture of this old building—known as "parkitecture"—was one of several prototypes for park buildings around the country. Today, the visitor center and museum highlight the ecology of Yellowstone Lake, focusing on birds. Also stop by to visit with a ranger and find out when ranger programs are scheduled, buy a fishing permit (payable by debit or credit card), pick up a souvenir, or take in some truly stunning views of Yellowstone Lake and the surrounding mountains.
