Construction Advisory: Construction will be taking place in the main campground near both restroom/shower buildings Oct. 2024 - May 2025 to replace the lift stations at the restrooms. Be prepared for construction-related traffic and increased noise levels. Porta potties are available for toilets. Showers and sinks may be limited or closed at times due to maintenance issues. Water and electricity may be temporarily disrupted when switching over utilities for a few hours at a time.
Due to safety concerns, walk-in entry and hiker drop-off/pick-up is not permitted.
The dump station and showers are closed to anyone not camping at the park.

Superstition Mountains Geology
Lost Dutchman in 1978The Superstition Mountains are the product of many natural forces that helped to shape this gorgeous mountain range over a long period of time. The Superstition Mountains are actually the result of intensive volcanic activity. They are composed of welded tuff (volcanic ash cemented under extreme heat), breccia (rock fragments cemented together with lava or welded tuff), granite, dacite, basalt, and some conglomerate. A few gold deposits pocket the surrounding areas. Some 25 million years ago, during the mid-tertiary period, volcanoes in this region emitted about 2,500 cubic miles of ash and lava, the ash spreading as far south and northeast as present-day Florence and Roosevelt Lake. The volcanoes collapsed into their partly emptied magma chambers, producing depressions or calderas. A subsequent up-thrust of thick lava within the largest of these calderas and the forces of erosion have created the Superstition formations that we see at the park today. Thick, alluvial fans spread outward from this eroding resurgent dome. The alluvial material is primarily tuff, dacite, and decomposed granite.
While hiking in the Superstitions, one can sometimes hear rumblings similar to rolling thunder. Geologists say this results from seismic activity resonated by the canyon walls. This could explain the origin of the Apache legend that these mountains are the home of the thunder gods.
