Occurrence Remarks:; Coordinate Uncertainty in Meters: 2.00000.

Occurrence Remarks: Occurrence Remarks: Prairie rattlesnake observed in the mid-morning on a gravel road. I almost stepped on the snake as I was walking back to my car after opening a gate I needed to drive through. Despite getting very close to the snake with my foot, it did not move from its coiled position. I took some photos and got my snake hook from my car to move it off the road so nobody would run it over or find it near the gate and harm it. The snake remained fairly calm as I moved it and only rattled briefly when I moved quickly around it. This was probably the calmest prairie rattlesnake Ive ever encountered. I took a few more photos and left the snake about 30 meters west of the road where I found it.; Coordinate Uncertainty in Meters: 29120.00000.

Occurrence Remarks: A 24-inch (+/-) specimen, found coiled and resting early afternoon within a shaded clay crevice in an arroyo bank. Note 1: After a few minutes close observation of the specimen by myself and my son, it uncoiled and slowly began moving away from us along the shaded crevice. It then lost traction and slid into open sunlight. Recovering slowly, it reentered the shaded area, which is where we left it. Note 2: Photo #s 10-12 are included to show the location in which the specimen was found. Note 3: A few minutes after driving away from the observation location, we discover a newly deceased second Prairie rattlesnake, likely run over by the only vehicle wed seen in the past hour.
