I met a guy named Sam while climbing here in California. Can’t remember what it’s called though. Kinda looks like reptilian don’t you think?

Once again, I used Google Lens to figure out where the location of this image was. Turns out to be a place called the “Lizard’s Mouth Rock” in Santa Barbara County, California:

The image given to us is a direct screenshot of an image posted by Maps contributor Jonathan P., although that has little relevance to the challenge.

Moving on, although we have the location of the image taken the flag is in explicit format, meaning that it’s somewhere on the internet wrapped with byuctf{...}. We noticed that a guy named “Sam” was mentioned, so we guessed that we could find him leaving a review of the place on a platform.

We checked through the following platforms: Yelp, Google Reviews, TripAdvisor, AllTrails — yet, we couldn’t find a recent reviewer by the name of Sam. Luckily, one of my team members searched up “Bouldering Lizard’s Mouth” (based on the challenge name) and happened to stumble across this website:

We scrolled down to the “Reviews” section and found this:
