To the west of the monument is a low structure which is protecting an
original portion of the crater area. Trinitite is visible through
openings in the roof.



It's the Schmidt house


The George McDonald ranch house sits within an 85'x85' low stone wall.
The house was built in 1913 by Franz Schmidt, a German immigrant, and
an addition was constructed on the north side in the 1930's by the
McDonalds. There is a display about the Schmidt family in the house
during each open house.

The ranch house is a one-story, 1,750 square-foot building. It is
built of adobe which was plastered and painted. An ice house is
located on the west side along with an underground cistern which
stored rain water running off the roof. At one time the north
addition contained a toilet and bathtub which drained into a septic
tank northwest of the house.

There is a large, divided water storage tank and a Chicago Aeromotor
windmill east of the house. The scientists and support people used
the north tank as a swimming pool during the long hot summer of 1945.
South of the windmill are the remains of a bunkhouse and a barn which
was part garage. Further to the east are corrals and holding pens.
The buildings and fixtures east of the house have been stabilized to
prevent further deterioration.

The ranch was abandoned in 1942 when the Alamogordo Bombing and
Gunnery Range took over the land to use in training World War II
bombing crews. The house stood empty until the Manhattan Project
support personnel arrived in early 1945.

Inside the house the northeast room (the master bedroom) was
designated the assembly room. Work benches and tables were installed.
To keep dust and sand out of instruments and tools, the windows were
covered with plastic. Tape was used to fasten the edges of the
plastic and to seal doors and cracks in the walls.

The explosion, only two miles away, did not significantly damage the
house. Most of the windows were blown out, but the main structure was
intact. Years of rain water dripping through holes in the roof did
