Fun, challenging trail to standing mill structure A real structure to see, not just a pile of mine tailings. The Sunflower Mine (a.k.a. National Mine) produced mercury. Inside the processing building which still stands, you'll find a large pipe used to tumble a reddish-brown ore called cinnabar. The fine particles were burned in vertical furnaces with coke to produce mercury gas. The gas liquefied after being cooled in U-shaped tubes. Located in Tonto National Forest. For current conditions call Mesa Ranger District (480) 610-3300. Rating: Difficult. Stock SUVs can reach Sunflower Mine. Difficult portion of the trail begins later. It becomes rocky and narrow with tight brush in places. One narrow shelf road with loose rock. Slippery when wet.
