Adventurer: The Abandoned Valley by Pdxaeroman

You're flying alone above southeastern Canada when your plane's engine sputters and dies, forcing you to crash land in a quiet valley surrounded by mountains. Your goal is to find a way to climb up stout mountain and enter stout mountain lodge, which has the radio equipment to call a rescue helicopter.

UNFINISHED - This is a pre-finish release, and many features may not actually be functional.
