Interesting nuclear warhead vs equivalent TNT volume and cost comparison starting at 4:14. Just the cost comparison in 1968 dollars: 10kt warhead $350,000; 10kt TNT $5,000,000; 2MT warhead $600,000; 2MT TNT $1,000,000,000 [thermonuclear weapons provide much more bang for the buck].
Project Rio Blanco
Project Rio Blanco was an underground nuclear test that took place on May 17, 1973 in Rio Blanco County, Colorado, approximately 36 miles (58 km) northwest of Rifle.
Three 33-kiloton nuclear devices were detonated nearly simultaneously in a single emplacement well at depths of 5,838, 6,230, and 6,689 feet (1,779, 1,899, and 2,039 m) below ground level. The tests were conducted in fine-grain, low-permeability sandstone lenses at the base of the Fort Union Formation and the upper portion of the Mesaverde Formation.
This was the third and final natural-gas-reservoir stimulation test in the Plowshare program, which was designed to develop peaceful uses for nuclear energy. The two previous tests were Project Gasbuggy in New Mexico and Project Rulison in Colorado.
Project Long Shot [an 80kt shot to improve nuclear test detection - great coverage of test hole creation and preparation - note that some post detonation survey footage associated with this test shot was incorrectly used in the Operation Grommet - Cannikin shot video found in my other therad about on the most powerful US underground test]
