Senticolis triaspis intermedia
Our plans to hike on the east side of the Santa Ritas were dashed by monsoon rains. So we headed over to the west side and saw these two snakes stretched across the road at the same time about 25 feet apart. Santa Cruz County, AZ. August 2008.

While herping with some friends from Germany in the Ritas for their first time, we saw this little guy on the road one late afternoon before a beautiful sunset. Santa Cruz County, AZ. May 2010.
A subadult seen early in the morning hours. Santa Cruz County, AZ. August 2018.
