Obsidian Mine?

[Nahui Ollin]

I found a location called Obsidian mine on the big mountain with the huge skeleton, but I see no entrance. Where is the entrance?

theres a bridge that goes into the mountain side right inside forge of obsidia turns into a cave and theres a ton of mining spots in there, look closely cause the only difference between obsidian and coal is obsidian is shiny
