Crooks Mound (French: Monticule d'Escrocs) (16 LA 3) is a large Marksville culture archaeological site located in La Salle Parish in south central Louisiana.

Archaeologists think it was a holding house for the area that was emptied periodically in order to achieve this type of setup.

[1] The site is on private land, usually with no public access, but it can be viewed from the roadway.

Pottery accompanied some burials; the weight of mound fill apparently crushed the vessels.

No evidence for domestic structures exists on or near the mounds, leading archaeologists to believe they were strictly for mortuary purposes.
