Hamilton's Hideaway

 is a small cave in the side of a cliff face in the Capital Wasteland.

This underground complex appears to be an abandoned military or medical research facility. It is mentioned by Sheriff Evan King in Arefu as a possible location of The Family as part of the Blood Ties quest.

Unmarked quest: Caching in with Three Dog
This is the area associated with the quest Caching in with Three Dog.

The cache is behind a locked cell door in the northwestern-most area, behind some rubble. It can only be opened by the key that is given to you by Three Dog.

Location

 * Hamilton&#39;s Hideaway can easily be found by traveling about a mile NE of Arefu into the river bed and following the cliff's rock until you find the entrance.
 * It's just north of Moonbeam Outdoor Cinema and just southeast of Northwest Seneca Station.

Enemies
The cave itself is populated with Radscorpions, Radroaches, and two, sometimes three Raiders.

Some of these enemies will be dead when you find them, because Radscorpions and Raiders will fight each other. Also, because the cave is quite dark in most places, even a character with very low sneak skill can easily pick off enemies from afar with Sneak-Attack Critical Hits.

Be careful when exiting this cave if you did not fast-travel to this location. There might be a large group of enemies waiting for you outside.

It is also possible to find Giant Radscorpions on some occasions.

If you have Broken Steel you might find an albino radscorpion as well.

Sometimes 3 dead wastelander bodies that may have spawned alive will appear.

I just did this currently have all xpacs and i had to face 2 albino radscorpions, 2 giant radscorpions, and a normal radscorpion so watch out

Scavenger
Just west of Hamilton's Hideaway, in line towards Arefu map marker, is a small metal shack with a Scavenger.

Notable Loot

 * Duck and Cover! - on the counter in the room with the Raiders along with Cherry Bombs.
 * Nuka-Cola Quantum - in the same room as above.
 * Bottlecap Mine - in the same room as the Workbench.
 * this place has a large amount of items used in schematics, most notable is that this place has all the items for a nuka grenade

In the weapons cache
You'll need a key to get in. See note about Three Dog above.
 * Guns and Bullets - on a footlocker
 * Mini Nuke - on a shelf
 * Stealth Boy - on a shelf
 * notable amounts of common weapons, ammo and grenades

And maybe (apparently random)
 * Power Armor - in a locker
 * Power Armor Helmet - in a locker
 * Power Fist - in a foot locker

Nearby
Due east by the river (you'll have to go around the rocks though, but it's pretty close and straight East) is a boat with some crates, a safe, and two ammo boxes. (Large brown boat in the background of the picture at top of page.)
