The northern passage is a location in the Mojave Wasteland located north of North Vegas. It serves as the starting point for the Fallout: New Vegas add-on Honest Hearts, as well as a checkpoint for the path to Zion Canyon. Jed Masterson and his hired caravan guards are present inside the cave.
A grave and a hollowed-out rock containing random minor loot can be found near the cave entrance. The rock has "The sun is killing me" written on it. The passage's interior consists of nothing but wooden supports and lanterns with an empty crate on the left.
Before Honest Hearts is downloaded, the northern passage is covered by a barrier of fallen rocks. However, when Honest Hearts has been installed, all the rocks have been removed, allowing passage to Zion.
