The Spring 2011 issue of Arizona Geology was posted online this afternoon. The feature article looks at new and old earth fissures in Cochise County and includes a spectacular photo gallery from AZGS geologists Joe Cook and Mike Mahan. One advantage of our electronic-version of the newsletter is the ability to offer extensive color photo coverage. [right, earth fissure in Sulphur Hills area, Cochise Co., AZ. Credit, AZGS]
