You have created another adventurous video, that looks quite exhausting, I believe because you are the whole time have to watch where you step so you do not twist your ankles. The canyon looks not red but sand color, every time you had a narrow passage I thought every moment it will be a hidden place with may be lost ancient cave or so. The Calcite you have found look like salt too. I hope you did not have any injuries and have a safe trip back. Thank you for doing this video!
