The cache is located on a bridge over Van Hyning Creek. What's the difference between a creek, stream, and a brook?
Generally, the difference is size: you can step over a brook, jump over a creek, wade across a stream, and swim across a river. But the distinction between them (especially creek and stream) is somewhat hazy, and depends on who named them and when they were named.
What's the difference between a 'crick' and a 'creek'?
One is a body of flowing fresh water smaller than a river, and the other is a pain in the neck. Unless you're from Appalachia, in which case the latter (crick) is an alternative pronunciation of the former (creek).
