This cave boasts some of the most classic (and difficult) sport lines at the Hood, and in the USA. Shade can always be found in the recesses of the cave, or under the nearby pine trees. Most of the hardest routes are found on the left wall, where you will encounter six 5.14s!! The hardest being Hasta La Vista, weighing in at 5.14b/c, and first redpointed by Christ Sharma. It is mainly through the efforts of Tony Yaniro that the harder routes here were equipped. He worked hard on some of his projects that others finally redpointed.

One route not to miss is the classic Straight Outta Compton a sustained 5.12d jug haul and the original route in the cave.

Follow the approach description for the hood, taking you through the switchbacks to the Corrosion Cave. Walk along the base of the cliff to the huge cave at the far right side. Please do not approach the cave up the hillside directly from the main trail. This will help reduce trail proliferation.
