“transport it down. (Suggestion: use a sled.)”

A catapult on the edge of a gorge would be more fun :)

Yea, maybe we could have some fun with this.
Catapult or Cannon works for me.
Make it a contest of innovative ideas to solve the problem.
Preferably using available materials and not lug heavy equipment up the mountain.
Maybe saw the top off spent oxygen canisters and make crap grenade launchers.
Or rockets, and get rid of them too?
Can't urine can be used to make one component of explosives?
