    As material slid into the hole formed, it closed the vent and the process repeated, eventually forming the huge hole. Blocks as large as 26 feet (8 m) in size were flung as far as 2.3 miles (3.7 km) from the crater. To the west of Hole-in-the-Ground is an even bigger maar, 1.1 miles (1,820 m), but older and more eroded, called Big Hole.
