Arroyo Milagro Chihuahuan Desert


Arroyo Milagro is the site at which much of the Colorado pinyon (Pinus edulis) tree ring research was conducted on the Sevilleta LTER, as well as re-sampling of historic BLM 1976 vegetation transects, and juniper-creosote distribution. Most of the pinyons and junipers that were at this site died out in the 50's drought.  This is the general area of Mesa Del Yeso, where there are extensive gypsum deposits.
