How about a rescue mission. Build a device crane etc. to retreive something off the side of cliff to make it a little more challenging have it in a tunnel about 5 to 10 feet in. I live in utah and we have great caves on side of cliffs.

possible solutions: build a crane with an electromagnet. build a crane with hooks. lower a barrel of water then let water out and push the thing in with a blast of water or air grab object and get out quick. other tricks to use egyptian mirrors to see like periscopes motion detectors with lights to find and cameras these may not be found in junk yards lol
