Old Indian Trick

Old Indian Trick
or How Long Until Sunset?

That's what my mother told me when I was a kid, that this was "an old Indian trick." It's probably not strictly Native American in origin and is no trick. It's a nice guide, though. Putting your hand on the horizon, each finger between the sun and the horizon is roughly 15 minutes until the sun sets. I use it when I'm out on my hikes, deciding how far I want to continue to venture away from my vehicle. I don't want to stumble back in the dark.
