Checkerboard Mesa Geology - Deep furrows in the shape of a checkerboard game, took millions of years to cut into the sandstone of Checkerboard. The horizontal furrows were made during the Jurassic period by wind-blown sands of huge ancient dunes spread out over land in place of the massive monoliths you see in Zion today. A freeze and thaw process is responsible for gradually widening the furrows along vertical joints. Notice that the carvings are always on the north side where snow takes longer to melt. The vertical slits were created much later after brittle rock had formed. There are etched patterns on smaller surfaces in the park, such as along the East Rim and Hidden Gardens. Past the east side of the park along US-89 between Kanab and Mt. Carmel Jct. evidence of crossbedding can also be found.
