What was special about the first nuclear test, rather than the thousands of others, at least hundreds of which were also in the Nevada desert?

Obviously it's historically significant, and the new forms of matter were first discovered there , so that's why trinitite is named after the site. But 80 years later, wouldn't we expect the other bomb sites to have just as many interesting chemical reactions?

It’s probably just that more people are looking at the trinity site because of said historic significance

The Trinity test took place in New Mexico, not Nevada.

Availability is probably the answer.

I have some Trinitite. It's easy to obtain. You can buy it in rock shops, especially in the Southwest. Back in the day, when they opened the Trinity site to the public a couple of days a year, there was no prohibition on collecting Trinitite. That's why rock shops have it.

They still open the site to the public one or two days a year but they won't let you collect Trinitite any more. You can walk on it but don't try to put it in your pocket or a person with a gun will pull you aside for a chat.

There's not much public access to the sites in Nevada; at least until the DOE resumes their bus tours and they're even more hard over about not letting you pick up anything.

We do. https://en.wikipedia.org/wiki/Trinitite#Similar_materials says "Occasionally, the name trinitite is broadly applied to all glassy residues of nuclear bomb testing, not just the Trinity test" and lists hiroshimaite and kharitonchiki as similar glassy residues from Hiroshima and the Semipalatinsk Test Site, respectively.

The general term for for the fused glass-like material formed during a nuclear test" seems to be "atomsite" - https://www.osti.gov/pages/servlets/purl/3001767 . Some images of atomsite from the Trinity and Semipalatinsk test sites are at http://www.radioaktivitaet.uni-bremen.de/downloads/Pittauero...

As a wild guess, what's special is it might be the easiest to get, with many samples to study.

"also in the Nevada desert" - huh? The first test was in NM. Probably irrelevant to your point, but...
