Being the newbie that I am I have zero knowledge or skill to edit any videos or such, so please forgive my horrible flying and video skills.  

Today the wife and I went 4x4ing in the Box Canyon area of the Santa Rita Mountains here in Arizona.  As we were climbing up to a plateau she saw a cave across a small ravine from us, so I had to investigate as best I can with my newbie flying skills.  Thought I would share as it looks pretty cool.  We're going to head back up there on Monday and see if I can get in closer and hover right at the mouth of the cave.  If all looks good (no bears or such) we're going to hike the ravine to investigate it first hand.

Here's a link to the video.  https://1drv.ms/v/s!AlqezZ7lgQsRrnxiN4qB...4?e=WMOpc0

That is pretty cool. Let us know what you find in there. The area looks pretty arid, so I would think you will find snakes rather than a bear. But who knows? That is the essence of exploration. Good luck.
