Rattlesnake Hollow

 is a location featured in Red Dead Redemption in the Cholla Springs region of the New Austin territory. It includes several small caves in the south face of the Redemption Mountains west of Twin Rocks.

Background
Bounties hide out here; Marston will be tasked with hunting them down and bringing them alive or killing them. Many cougars and coyotes also live here, so be careful when traveling through or hunting (for bounties or otherwise).

Animals
There are relatively few animals found in Rattlesnake Hollow. The few that are there include:
 * Cougars
 * Coyotes
 * Wolves
 * Bighorn Sheep
 * Horses

Layout
This area consists mostly of steep hills and hollowed-out rocks. On searching the cave openings, one of them contains a chest with cash inside.

Trivia

 * Despite the fact that it is named Rattlesnake Hollow, it does not contain any rattlesnakes.
 * Roughly in between here and Rathskeller Fork, directly west of Pleasance House, atop a hill is a large, abandoned campfire (this is most probably Hamlin's Passing).
