Help me, Doctor Internet!

I'm remembering an Apple II (or Apple IIe) game I played in second grade, which would be about 1982) that was one of those text adventures that was text on the bottom and very pixelated art on the top. It took place in the old west.

My brain is saying it's called "Serpentine" but all the research I've done says that's a completely different game, but was out around the time of that game.

Any ideas?
