Water, wind, and calcite erosion in per-volcanic sandstone formation. Slightly acidic rainwater seeps into the sandstone during winter rains and dissolves some of the calcite. Warm and dry days cause the moisture to pull the dissolved calcium back out of the rock, causing holes and caves to form. Watch for peregrine falcons and other birds of prey nesting high up in the Castle Rock caves. The upper trails are closed Feb-July to avoid disturbing the nesting birds.
