Wiley's Well is popular with rockhounds. They have been coming to Wiley's Well since the 1930s with the discovery of geode beds. Even though Wiley's Well has been very popular with rockhounds over the decades, the area remains rich with such minerals as chalcedony, citrine, quartz crystals, rhyolite and jasper. Though winters are mild, making the campground popular with visitors who visit every year from colder areas, summer can be extremely hot with recorded temperatures as high as 130 °F/54 °C.
