Jello Tower is a 4,510-foot sandstone pillar in the Park Avenue area of Arches National Park in eastern Utah, rising steeply above the Park Avenue Trail within one of the park’s most dramatic rock corridors. Formed from Entrada Sandstone, with the Slick Rock Member over the Dewey Bridge Member, it is part of a broader landscape shaped by runoff draining through Courthouse Wash toward the Colorado River. Its first recorded ascent was made in November 1986 by Charlie Fowler and Sue Wint on the route Soft Parade. The tower also appeared in the opening scene of the 1989 film Indiana Jones and the Last Crusade and remains a protected scenic landmark.
