Trip Report: Jaunts

First published in 2021-24. Reformatted 2025.

This page is for various minor adventures that, by themselves, do not warrant individual trip reports. This page covers the time frame starting in July 2021. See Variation Authorized for similar material from 1994 through 2004, Miscellany for 2005 through July 2007, and Wanderings for material from 2007 through June 2021. Unlike my "normal" trip reports, this one is alphabetical rather than chronological. Just a reminder PIN means Permanent Installation Number and ILC means Installation Location Code; I include these codes for Air Force properties when I know them.

Cottonwood Air Force Station
Cottonwood, Idaho
PIN 3294, ILC ENYW
46-04-01 N, 116-27-51 W

This property was assigned to Air Defense Command on 21 December 1955. It was listed in the 1956 USAF Installations Directory with identifier SM-150; this was changed to Z-150 on 1 July 1963. The property was inactivated on 1 March 1965. I visited the former operations site in August 2025. The former support facilities are further down the hill and now occupied by a prison. The former housing area is at the edge of town and I drove past it without stopping for photos.

Gasbuggy Nuclear Test Site
Dulce, New Mexico

This was not a military site. The Atomic Energy Commission detonated a nuclear device here on 10 December 1967. This was part of Operation Plowshare, which looked for possible peaceful uses of nuclear devices.

Liberal Army Airfield
1.5 WNW Liberal, Kansas
37-02-40 N, 100-57-50 W

I visited this WWII airfield back in August 2007. I returned in July 2023 and viewed this hangar from the nearby Mid-America Air Museum, which is well worth a visit.

Lonestar Pecos Electronic Scoring Site
aka Rattlesnake Electronic Scoring Site
17 SW Pecos, Texas
ILC PECO
31-13-02.1 N, 103-39-35.6 W

The term electronic scoring site (ESS) replaced the earlier term radar bomb scoring site (RBSS). This property was activated in 2001 and the facility began operations in 2002. By May 2011 the Air Force had declared it surplus and it was available for disposal through the General Services Administration.

This was an Army depot from 1942 to 1948, then again from 1950 to 1955. It was built for the Army Service Forces but is similar in layout and building design to Army Air Forces depots from the same time period.
