- Helen S. Carlson, "Nevada Place Names: A Geographical Dictionary," p. 126. Granite Spring Valley extends from Copper Valley to Adobe Flat and is bounded by the east by the Trinity Range and on the west by the Sahwave Mountains.

- The Blue Wing Spring and Ragged Top SW maps indicate that this is in T25 R26 S 24, S25 & T25 R27 S19, S30. The Pershing County Assessor shows that this is a checkerboard of BLM and former Santa Fe land, now owned by a holding company

- Matt Hensarling posted that this was the Copper Valley Nuclear Test that was cancelled because of fears of creating "fault slippage" that would result in earthquakes.
- Craig posted that it was something to do with Project Gondola, which was part of Operation Plowshare. Project Gondola was cancelled after there were problems with Project Faultless.

- Xelex continues: "Arc arrays are typically used for collecting fallout samples from surface (or shallow subsurface) bursts. If the Plowshare shot Gondola was to be an excavation test, it would make sense to collect fallout data."
Project Gondola
- Not to be confused with Pre-Gondola
- Scott Kaufman, "Project Plowshare: The Peaceful Use of Nuclear Explosives in Cold War America," p. 225 (not available in Google Books).
- "The Off-Site Plowshare and Vela Uniform Programs: Assessing Potential Environmental Liabilities through an Examination of Proposed Nuclear Projects,High Explosive Experiments, and High Explosive Construction Activities Volume 3 of 3," In 1969, a nuclear cratering experiment was in the planning stages. One of the four sites under consideration was the Black Rock Desert! However, no field work was done.
