Jackson Lake

 fishing area, lake

Jackson Lake is a small body of water located in a canyon east of Wrightwood and Big Pines. Jackson Lake was formed by the San Andreas fault, and is mostly fed by snow runoff from the mountains. During summer months, many fishermen utilize Jackson Lake, as it is the only real place to go fishing in Wrightwood. During winter months it isn't uncommon to see the top of Jackson Lake frozen over with ice.

SAG POND
A sag pond is a body of water, which forms as water collects in the lowest parts of the depression that forms between two strands of an active strike-slip fault.[1] The relative motion of the two fault strands results in a stretching of the land between them, causing the land between them to sink.
