I think that depends on how far away the mountain is from base, how long you stay on top of the mountain and whether or not the helicopter is still running while you are working due to the cold and altitude. An hour in a helicopter in Alaska runs about $1800 last I checked and they bill in 15 minute increments only when the engine is running. One of my clients is a Temsco Helicopters in Juneau ;)

One device that is showing a lot of promise for Alaskan environments is the Sterling external combustion engine, running on diesel. No installations yet but testing continues. http://www.whispergen-europe.com/ In Alaska we often used micro-filtered #2 diesel fuel and inside, heated auxiliary holding tanks with redundant pumps. We also installed dual 6kw, deep-sump gennies with a smart controller that did exercising and supported fail-over operation. One helicopter flight to an Alaskan mountain top typically cost about $10,000.
