In my days in the Aleutians, a few times after an hour of helicopter ride over open ocean, get fogged in. Land on the beach. We would saddle up our backpacks with batteries, test gear, spare radio and amplifiers,antennas, hardware etc.. 15 gallons of water for the zinc air batteries and go hiking 5 or 6 hundred feet up a mountain side through thick alders. If you don't know about alder bushes, see wikipedia.
Get to the seismic sensor location and inevitably we would be missing some critical item.
The standard line was: I thought you had it in your pack.
I would radio the helicopter pilot to rummage around and find it, if not fly back to base and get it. Pilot loved it, both for the humor and razzing he could dish out, and flight time logged.
Mercifully it was always the grad student/field assistant get the joy of hiking back down to meet the heli pilot and hike back up through the mess.
It was great training for their future leadership skills as chief scientists.
There must be moderation in everything, including moderation.
