The scene was inspired by pictures of the world's largest crystals (alas, not diamond!), discovered in a Mexican cave not too many years ago.
The contest limited entries to a ten-inch cube of shelf space...I wanted to build something that occupied most of that volume, not just the "floor". But I couldn't decide on a theme at first. When my girlfriend suggested archaeology, this concept immediately...ah...crystallized.
As someone who rappels into caves as my other hobby, I really love this! I never thought to do a caving MOC! I would love it if you could make the photos show up larger and give us more descriptions of what is happenning in the scene!
