There are dozens of creeks named "Fish Creek" in Alaska, including across Cook Inlet, and near Hyder, near Ketchikan, and near Juneau. Please note in your logs other creeks named "Fish Creek" that you know of.
This cache is about the size of a tuna fish sandwich but some cachers might find it challenging as it was hidden with a lot of container mischief™. Be careful on the pavement path as this spot can be very busy with cyclists, skiers, joggers, hikers, walkers, tourists, and rented e-bikes and you don't need to be on the pavement to find the cache.
