Aerial view of the ground around Cassadore Spring

The orange dot marks the spring, in a frame about three quarters of a mile wide.

Cassadore Spring, about twelve miles out of San Carlos town, sits inside Gila County, Arizona, on San Carlos Reservation land. Tepid water, low seventies. No one has written down if visitors are allowed, and on reservation ground that means assuming you need permission until told otherwise. No water sample, no USGS number.

Location

A few dozen feet from Indian Route 1100; roadside. Upland country with a mild yearly average, modest rain and a little snow. The land unit is the San Carlos Reservation and the designation is tribal. Timber Camp Recreation Area is the closest listed campground, roughly sixteen miles away.

The file says winter. Everything about going depends on the reservation: access is unknown and there is no public-land status to fall back on. Contact the tribal authorities before driving out. The temperature is too low for soaking in any case. No fee is listed.

Terrain

USGS hasn't flown a detailed laser scan here yet, so this view comes from aerial photos and older elevation data.

Heat Below
79 milliwatts per square meter of heat flow

That's close to the US average of 65. It's higher than at 14% of the springs on this site.

Heat flow measures the warmth working its way up through the ground from deep inside the earth. Where it runs high, rain and snowmelt that seep down through cracks in the rock come back up hot.
