I’m not so strange. Just an inverted mountain range! Stand in my middle, it’s uphill both ways!

I'm worked by owls Who shun the sun Mind the gap now My word, they have none

I leave a trail you cannot see, yet clever noses follow me. A hound may chase where I have been, what am I drifting on the wind?

A snake, a snake Snake, a snake Oh, it's a snake Mushroom, mushroom. Who's missing?

I silence rivers, lock the lake, yet vanish when the warm winds wake.
