As I rush to get back to my uncle I cause a landslide! The lower gravity here must make these caves less stable!

Although the rocks don't weigh much, they are pushed by higher rocks that weight more. When this land slide finishes, this cave will be blocked forever!

I have to decide quickly! Should I go down towards the centre of the Earth? Or should I go up toward my uncle? Either way, I will never be able to use this cave again! Or should I do something else?
