I see no impact at 37°32'21.01"N 116°33'59.93"W

I see a hilltop instrumentation or camera pad.

I don't see signs of them digging a big hole to dig up a test weapon
it must not have gone deep.

You would also be able to see the changes in the earth surface from the weathering of the impact area by going to the clock face(show historical imagery) at the top of the Google earth page and rolling back the image to in this case April 22 2006
When you go back in this case there is no changes.

When you bring up the historical imagery date bar and slowly go back and forth you see no changes from photo to photo.

I use satellite imagery for looking at the earth surface for mining.
I have found a lot of neat tricks on Google earth.

I have even got lucky and caught friends on days they were at there mine because there truck appeared and disappeared.

If you want to see this affect try 37º 13' 43.56"N 115º 48' 37.10 W and watch the building appeared and disappear
