Hi Al,

But if Lapaz also arrived on the scene as shortly after Nininger as it
sounds, unless Nininger invited him, it is because so local tipped off
Lapaz which increases the liklihood the same was the case with
Nininger. Is there any reference there as to whether the mass was
found without any tips, as I believe the question was trying to
identify which meteorite was recovered in the field first by the person
doing the triangulation, a small fact which easily can be overlooked.

I would expect some meteorites were recovered in a similar fashion in
the end relying on tips from the locals with general triangulation
information - even as Martin points out, Lost City and I would add
P??bram years earlier, by local witnesses.

The latter 1959 fall was called P??bram, but really found at the small
population of Luhy. Perhaps if not for the triangulation this
meteorite would still be in the museum with the official name of Luhy,
had it not been for the triangulation exercise with the sky-cameras
which only lead getting the general area of the fall, but not
necessarily exactyly into the strewn field.

Kindest wishes
Doug

him and refers to them frequently)

Greetings,

Harvey Nininger who witnessed the November 9th 1923 super bright meteor
fall
at McPherson, College, made his eye witness notes and went on to contact
newspapers, witnesses on each side of the fall. While this particular
use of
triangulation did not yield the actual meteorite from the fall
withnessed,
it did result in several other meteorites being found.

Harvey used this method many times. He used it with the Norton County
fall I
believe and was able to locate that meteorite with triangulation. He was
standing on the meteorite in it's pit when Lincoln Lapaz and his group
walked over to the site.

I'll have to look up and try to put together various meteorites that
Nininger found using this method.
Best!
