Our trip had been replete with rattlesnakes. The roadways and rockcuts in the Big Bend area had offered up a western diamond-back or two, a few Mohave rattlers, many black-tailed rattlers and a sufficient number of mottled rock rattlers to keep things really interesting. We had found rock rattlers having pearl gray ground colors on some cuts, those having a bluish-gray ground color on other cuts. and Kenny had found and shown us one from a more westerly cut that resembled a banded rock rattler as much, or perhaps even more, than it did the mottled subspecies.

But the ones that most caught my attention had an olive-fawn ground color with faint pinkish overtones and warm brown irregular barring. In color they looked far more like the rock rattlers from the rather distant Davis Mountains than the populations nearest to the snakes at hand. And their colors camouflaged them more effectively than those of any of the other populations we visited.

Judge for yourselves how inconspicuous the warm overtones rendered these rattlers when they were lying quietly amidst the rocks and soils of their natural habitat.

For us the question quickly became how many had we overlooked rather than how many we actually saw.
