In the book, Tilden, an explosion from 1946 near the Big Southern Butte is referenced. Watch this video of it, an actual occurrence: https://imgur.com/t/tnt/6AgOCpP

As the protagonist Henry mentioned, earlier explosions occurred in the prior year, almost immediately after WWII's end, though all of them smaller, varying from 125k pounds of TNT to 250k, half as large as the 1946 blast.

The TNT explosion referred to in Tilden occurred in the fall of 1946, was

indeed a half million pounds detonated just a half mile from another million and a

half pounds of TNT stored in an “igloo”. See the blast on this link:

Similar, though smaller, blasts took place throughout the prior year, the end of

WWII apparently just a springboard for preparing for the next offensive. Here’s a list of

the blasts:

October 18—125,000 lbs. detonated

October 19—125,000 lbs. detonated

October 30—250,000 lbs. detonated

October 30—another blast of 250k

October 30—another blast, smaller at 125k

October 31—250,000 lbs. detonated

October 31—a second blast of 250k

There were other blasts, with reports of being heard in Oregon and felt in California.


The tests occurred at Scofield, northwest of the Big Southern Butte, within what is

now the confines of the INEL. The biggest blast sent a plume a mile high, and the

plume of another reached over 2000 ft. high just two minutes after detonation.
