The number of deathclaws found atop the promontory varies with the player's level. If the player is a high level, 30 or so deathclaws, potentially including multiple mother and alpha males, may appear. See also "Bugs", below.
pcps3xbox360 Not all deathclaws in this area may appear when arriving at the location for the first time. The remaining deathclaws will typically re-appear once the player has fast traveled or, notably, when the player loads a save. The latter may result in the player's death if the save was made while on the promontory itself. For this reason, it is strongly recommended that at least one save be made (and kept) prior to climbing onto the promontory. [verified]
pcps3xbox360 Similar to the above bug, the dead prospectors may not appear on the player's initial arrival at the promontory. Saving and reloading, fast-traveling, or waiting for several hours should solve this issue. If this does not work, save the game, and turn off your console (If on PC, just close the game) and turn it back on and load the save. The bodies will be there now.
Sometimes bodies, and other game objects fall through the ground and are in-accessible. The only remedy is to wait for the game to reset the objects in the map cell to their original positions. This requires seventy-three in-game hours spent away from the area, and is unaffected by saving and loading. [verified]
pcps3xbox360 It is possible for an 'invincible' deathclaw to spawn here. Even when it has lost all HP it still lives and cannot be killed. [verified]
pcxbox360 Using Archimedes II in this area can result in the red targeting lines randomly triangulating all around the area (orbital laser will not discharge either). This was not fixed by saving/reloading. However, upon fast traveling, the orbital laser can discharge, scoring a direct hit on the player, causing serious damage. After several save/loads, the targeting laser glitch remains present whenever this area is visited. [verified]
pcxbox360 Sometimes, after clearing the area, several more deathclaws will all spawn at the same time and in the same area. Sometimes these deathclaws include mother and alpha male deathclaws, even at lower levels. [verified]
xbox360 Getting the Remnants power helmet from Silver Peak Mine before going to deathclaw promontory solved above problem. It's a good idea to take the Remnants power helmet with you when you head to the deathclaw promontory, or when returning if you encounter this glitch.
xbox360ps3 Sometimes, the deathclaws will run into the water where the entrance is and will not return to land. [verified]
xbox360ps3 In rare instances, deathclaws won't spawn in the area. [verified]
pcxbox360 Very rarely the deathclaws will spawn in the little dirt area before the entrance, there will be a mother and 4 alpha males. If so, head back and wait 24 hours (in-game) and they should be pushed back into normal area. [verified]
pcxbox360 If not liked by the legion and you wait there legionary assassins may be sent after you. If you're camping on a high rock to snipe, the legionary assassins may get stuck in the rocks, unable to be killed or hurt. [verified]
