Friday: Inside the NTS

The amazing alpha rope--seemingly ordinary nylon cord keeping the world shielded from alpha particles.

Danny Boy, 0.42 kilotons detonated in the dry basalt of Checkerboard Mesa. The burst depth was 34m underground and the resultant crater measures 66m across and 19m deep.

Jay shows that the melt glass (black stripe on rock) from the Danny Boy explosion is still incredibly radioactive.

This was as close as we got to Schooner, 35 kilotons detonated 108m underground. The crater is 260m across and 63m deep, approximately 1/4 the size of Meteor Crater and similar in morphology. Below is the glossy 8x10 of Schooner provided by the NTS PR office.
