Stinking Springs
Stinking Springs earned its name from hydrogen sulfide gas discharged with the water, creating a distinctive smell at this 81-degree Fahrenheit spring in Rio Arriba County, New Mexico (though historically included in Colorado databases). The spring's striking iron and sulfate chemistry is unique among regional thermal features.
The approach requires a 230-meter (755-foot) walk through high-altitude forest typical of the Sangre de Cristo Mountains. At 7,557 feet elevation, the landscape features spruce-fir forest with views opening toward the Navajo River valley. The water's high iron and sulfate content (470 mg/L sulfate, 140 µg/L iron) colors the ground around the spring orange and yellow.
Stinking Springs marks the boundary region where Colorado and New Mexico geothermal features blur together. The spring's calcium-sulfate chemistry and characteristic odor indicate water that has dissolved minerals while ascending from deep circulation zones. Historical records indicate use by indigenous peoples and early settlers despite the unpleasant aroma.
The 755-foot walk to the spring is moderate in difficulty. Winter snowfall (78 inches annually) restricts access November through early May. Best visits occur June through September. The hydrogen sulfide smell is intense at close range; plan a short visit if the odor bothers you. Bring water and sun protection.
