As most of you reading this will agree, the Chicago workshop was a blast and an excellent learning experience. It was revitalizing to be around other young people and the weather was a nice break from the desert heat. In the short amount of time I made a lot of friends and learned a great deal from the workshops which I am now applying in the field. I felt the Chicago experience really enforced a sense of pride in the collective efforts of all us interns and our commitment to being good stewards of the environment, especially to the plants.

The first day back to the Mohave we met up with some wildlife biologists doing bat research on the lower Colorado River with the Bureau of Reclamation. The location was a small re-forested cottonwood and mesquite forest on Native-American reservation land. This patch of forest was put in place in an attempt to imitate what the floodplain ecosystem may have looked like before damming up the Colorado and altering the periodic flooding which maintained these types of habitats. We set up a series of mist nets along corridors between the trees and spent the next 4 hours or so going from net to net, retrieving the captured bats out of the nets and recording the species, size, and sexual maturation. It was an extremely successful night with 44 bats being captured.

Over the weekend one of the ladies from our office took Steve and I out fishing on Lake Havasu, and although we only caught one fish the whole morning, we got to cruise through the cliffs of the Topock Gorge which was absolutely gorgeous (pun intended). In the Mohave language the word Havasu means blue water and it sure was.

One day we got sent out to monitor a spring where there was an infestation of a non-native tamarisk down a steep-walled canyon. Along the upper portions of the flat rock there were numerous petroglyphs drawn onto the weathered stone. The enigmatic images were all different shapes but I noticed a recurring image of what looked like an incomplete figure 8, and an even-sided cross. One small drawing even resembled a dinosaur

As the mercury continues to rise each day, seed collecting becomes more and more difficult. The other day it reached 113 degrees farenheit during the day and only dropped down to 102 at night. It’s unreal how much water we drink each day. We have been seeing many wild burros and have even caught a few fleeting glimpses of desert mule deer. I can’t even fathom how those animals survive in that heat every day. Until the next hotter week.
