I wondered if the renovations to the Union had affected this BM. I think this one may be gone, sadly.

Was able to find benchmark using previous finders picture.

Found this one while looking for an older one near by. Easy to spot

found it.

We found this at these coords from previous logs. Had to duck the campus security to avoid questions this late at night, all the ambient light made easy pictures.

Psychly and I rode our bikes over to this one in the evening and went right to it thanks to the coordinates from Fenix6372.

Found it. That's all I can say

my first logged find!...too easy for a surveyor, moving on to a challenge.

Found this one today between classes. I just looked over and there it was.

Found it from the description. It's in the flat part of the raised garden retaining wall, on the east side of it.

Found this log, but was in a different place than the coordinates were given. Had to read the description to find this ultimately. N33 12.685 W097 08.811 are the coordinates I logged with a 12 foot accuracy. Hope this helps others.

Found it in good shape.

Found this one in the concrete of a flower garden by the University Union, it isn't in the ground like you might think. I had coordinates a bit different than what is listed, will post them here.

Couldn't find it. Looks like all new concrete on that side of the building.
