Visitors in hats and coats stand behind a railed boardwalk at the rim of the Mud Volcano, a cracked, steaming paint pot in Yellowstone National Park. The crater is about thirty feet across and sends up frequent bursts of steam. The printed caption notes that it has had no violent eruption since 1898, though in 1870 N. P. Langford watched an eruption throw mud several hundred feet high. The site sits along the Grand Loop Road and was an early stop for park tourists.
