Trying to find an old Macintosh game from my grade school years

Every now and then I get a stint of nostalgia and most of the time it's for things I can't remember very well. In this case, a game from my grade school years on a Mac.

I don't remember the model of the computer, but it had to be 95-97, based on what years I played it. It was an adventure type game, in a snowy mountain, with a character I want to remember wearing a green parka. I recall some games involving scales and calibration weights and maybe something with gems. I know there was a lot more to it, but that's all I can ever recall... and I want to replay it at some point, just because.

I wish I had some more info, but I've known Reddit to come through on things like this. You guys are awesome, thanks for helping!
