In 2020, an email came into our survey requests from our study area in the Phoenix Mountains. A hiker had seen a rattlesnake in ambush on the trail, on multiple days. I got information and planned on heading up there to see if this was one of our tagged snakes, and if not, make that happen. I figured that based on the description and the snake's staying put over several days, that this was one of the many unauthorized spider trails that lead all around the mountain and not frequented by human feet, and that there was plenty of time to make it up there.
3 days later: up on the mountain, here's what I saw: a Speckled Rattlesnake coiled fully in the open, a few feet from where it was described earlier in the week. As I set up a working area and took out equipment needed to process the snake, a couple of hikers approached. I told them about it and they routed appropriately. Then another group, which did the same, followed soon after by a couple of guys on bikes and a woman and her (off-leash) dog. This was all within the span of about 2 minutes, and the reality of these snakes was revealed then.
This snake had been not noticed, and likely stepped right over, possibly a hundred times in the past week. The snake didn't reveal its position, and didn't need to, since its exceptional camouflage was doing its work. This is normal, and happens across all desert parks throughout the year. This is what rattlesnake encounters usually look like: a one-sided observation by an animal who remains hidden as we walk right on by.
We often get comments on crypic rattlesnake photos like "I would have been bitten"! or "I would have died for sure!", but that's the least likely situation, regardless of if the snake was seen. The most likely scenario, in the event that a rattlesnake isn't seen and is on a path we're on, is that we'll just keep on moving, and finely-tuned crypsis evolved over millennia will keep it from being discovered.
And of course, in the event that this fails, they have their famous warning system. Even then, the action is almost always to escape, appear dangerous, and get time and space to evade the threat.
Yes, bites do happen and if someone were to step directly on this snake that's a possibility. But the numbers of these instances are low, even in this area where multiple species of rattlesnakes and thousands of weekly visitors share space, the overwhelming fear that these animals occupy in the minds of most is hard to justify.
The snake was tagged and measured, then released under a boulder just left of the photo.
