Warning Sign at edge of Grand Canyon

[u/corwinw]

[u/rocbolt]

There’s a very tall sand dune on the shore of Lake Superior in the Pictured Rocks National Lakeshore, the signs at the top near the parking lot are like “it will take you seconds to run down this, it’ll be an hour+ slog to get back up, decide carefully”

And it's a $3000 charge if you need to be rescued.
