Mastodon Mine

Overview

Mastodon Mine is a compact slice of park history tucked along the Mastodon Peak Loop in the Cottonwood Springs area. You’re in the park’s low, Colorado Desert zone here—think palms, rugged hills, and broad views rather than Joshua trees.

What You’ll See

The mine site itself is a photogenic cluster of ruins: a stabilized ore bin, concrete foundations, and scattered relics from the gold days. The loop threads sandy washes and rocky steps; in spring, you can catch wildflowers painting the desert. Start through the Cottonwood Springs Oasis, then swing past the mine and, if you’re game, pop up to nearby Mastodon Peak for sweeping desert vistas.

Trail & Difficulty

Plan on roughly 2.5–2.6 miles with about 440 feet of gain on a well‑signed path. Most of it is straightforward walking, but the optional summit of Mastodon Peak adds a short, fun scramble. Expect full sun and some sandy stretches that slow the pace.

History & Geology

Gold was found here around 1919, and the mine saw intermittent activity through the 1930s up to 1971. It worked a gold‑bearing quartz vein via a 75‑foot inclined shaft until a fault severed the main vein and operations ceased. What you see today—ore bin (stabilized in 2015), foundations, and nearby mill remnants—tells the story without the crowds or fencing you’ll find at bigger sites.

Wildlife

Keep an eye out for large lizards basking on warm rock and typical desert birds flitting through washes. Sightings vary with season and time of day.

Tips for Visiting

There’s no water, shade, or facilities at the mine; everything is at the Cottonwood Springs trailhead and campground. The desert sun can be brutal—bring plenty of water, sun protection, and sturdy shoes, and save the mine structures for photos only.

Best Time to Visit

Spring and fall bring friendlier temperatures and, in spring, wildflowers. Aim for early mornings or weekdays for a quieter loop and softer light. Midday sun here is harsh for both hiking and photography.
