The purple agates locally referred as "Bean Agates" which can be confused with more known Bean agates from Mexico (ones with "eyes" all over). They're one of few amygbdaloid agates found south of Deming, New Mexico and they're generally white to gray, sometimes with pink, yellow and purple hues. They're always small and the largest agate I have seen is about 3 centimeters. Some agates with poorly silicified "peanut" inclusions had been found.
    The agates can be found around the corral at Hermanas but since the land is mostly private, the collecting is not encouraged. There are real stories about the land owner shooting some warning shots at the trespassers and I know a certain collector who almost got shot. The agates can be found along the Hermanas road itself which is considered a public land. I have found a number of agates by just walking down the road after it was plowed in preparation for road paving.
