Came across this interesting little bridge while hiking the area and decided to hide a cache here. Looks like someone spent a bit of time constructing this mountain bike bridge here and even made a sign to go along with it.
You're looking for a test tube like container with a log and pencil inside. It's a combination between a micro and small so it's listed as other since it's right in the middle. There area around where the cache is hidden looks like it can get a little spongy and maybe flood so the terrain is rated as a "3".
Please rehide as found and make sure the white cap isn't exposed.
