I too have no pictures but have always had an avid interest in the early forts.
Ft. Sumner from here is about as close as anywhere else. Old Ft. Sumner was an adobe fort built on the east bank of the Pecos. I was at the Monument / Museum one day and ask the manager Gregory Smith if it would be possible to raise funds, obtain a grant, locate the original foundations and restore part of the old Ft. In 1908 (I believe) a flood melted / swept the remaining houses and ruins away, leaving hardly a trace. Gregory said that there were no foundations. The government was in such a hurry to build it that the adobes were laid on the ground.
The fort buildings were purchased by Lucien Maxwell (famous for the Maxwell Land Grant) and he roofed over the old original flat, dirt roofs on some of the better buildings. In the picture below, the house in the center was the Officers Quarters and that is the house that Maxwell moved into and it is said that Billy the Kid was killed in the closest corner room.
The Pecos River has eaten 3/4 of the ground that the house stood on and a low mound now exists where the front of the house was.
Speaking of the flood.....the flood also covered the old ft. cemetery up, washing away the graves. When I was a kid, (1961) Lincoln County sued De Baca County for the remains of Billy the Kid. The proceedings were held in Ft. Sumner and for a quiet, rural New Mexico county, this was a big deal and big news.
Testimony was given in court that due to the flood, they didn't know where Billy the Kid was actually buried and no one else did either. In 1962 a Federal Judge agreed and that was that. That fact sure hasn't been advertised.
