This was definitely more challenging than I had expected, but well worth it in the end. We made it up to the abandoned Old Spanish mine, which is past the trail end marker, and we even saw a few bats and a gila monster. I think it took us around 4 to 4.5 hours, with a good 35 minutes exploring around the mine, and hopefully next time we'll attempt Finger Rock.
OH! If it was one of you who put the fake skull inside the mine, good job, you had me screaming like a little girl haha
