Three Main Types of Volcanoes* The three main types of volcanoes differ in shape, size, and make-up; the […]
Utah’s sandstone units tend to be exposed on the flanks of large gentle uplifts, which because these brittle layers are sandwiched between ductile shale layers, tend to form extensive joint systems which run perpendicular to the direction of the folds and parallel to the stress fields. Here’s a example pic where the joints are highly visible..
Keeper potholes are found in slot canyons. In the recent decades “slot” canyoneering has become a major sport, and very few areas of the world have nearly the number or diversity of slot canyons as southern Utah.
