This map is a smaller version of Camp Crystal Lake. It is roughly 45% smaller in terms of total play area.
The map is modeled after the setting of the same name from the original Friday the 13th (1980).
Since Jason was not present as the killer in the original film, this is the only map where, technically, Jason wasn't supposed to be in.
However, since Jason was secretly alive during the events of the first film and witnessed his mother's decapitation, then likely Part 2 Jason is supposed to be on this map.
Oddly enough, the main cabin was that present in the original film doesn't appear to be in the map anywhere. Thus, this is the only map where there isn't a main house that remains spawned on the map.
The intro cinematic is different than the standard map. In the Small intro, Jason emerges from the water and drowns Rob Dier.
