Found this for Windolph’s 6th period!

I work near the Capitol and walked over to locate the Benchmarks located on the grounds. I would like to find an older photo of the monument, just to see what it looked like originally. This is my 2nd Benchmark.

First benchmark type is a bolt. Used previous posted coordinates to assist in location, though it is not hard as the block has been preserved.

Pretty cool finding a benchmark that is as old as this one. Glad it is still here.

Found near the capital building while visiting Austin and picking up virtuals on a business trip. This was more challenging to find in the dark with some locals nearby.

Logged this right after finding nearby AUSTIN LONGITUDE STA disk. Two monumented benchmarks within 20 feet of each other! This is also the oldest benchmark I've found, by far (monumented 1872). Glad I took the time to walk around the capitol grounds after the building tour.

i thought this was a BM glad to find it is

Found it! Doesn't look like much but don't let its ordinary appearance phase you. After all, what else would a bolt be doing stuck in the middle of some concrete?

Found while visiting the State capitol. Benchmark is in nice shape.

The "bolt" is in the top center of the limestone block. The station is on the lawn west of Brazos Street. Other markers close by are: BM0627 Austin Longitude, BM0900 Austin Capitol Dome Liberty Base & BM0901 Austin Capitol Dome Liberty Star.

The bolt in top of the cut limestone block. I have located several other bolts and this is the first one that appears to have been driven into place mushrooming the end. There is no cut cross or B M stamped on the end of the bolt.

Found this one in the early morning and did my best to take a picture.

Interesting to see this categorized as a bolt, because it really looks like a railroad spike. I've logged a few of those before, and don't recall any being listed as bolts. Anyway, appears in good condition, solid, and as described. I didn't average but my coordinates showed about .448' and .337.

We parked nearby but moved and ended up on the other side of the capital. I hiked over to get this pic! THANKS! I find it interesting this as been used as a maker since 1872!

I'm amazed this has been a marker for well over 130 years! May she guide those who seek for many years to come!

Found while out on a Saturday evening ride.

My wife and I visited Austin this week. I stumbled across this benchmark while we were strolling the Capitol grounds.

This is very interesting! Liked stumbling across this one!

Actually stumbled across this benchmark by accident. I was on my way to the Archives building and looked at these two strange concrete pedestals wondering what they were. Found this benchmark disk on one of them and a strange bolt in the other. Found out when I got back home that they were both benchmarks. Wow! This mark was located in good condition at the place described.

Great location.

This benchmark is on the State Capital Grounds.

Now I know the meaning of the bolt.

Found this one today on a virtual caching tour of the Capitol area! What a gorgeous day to be out! I wondered what was so significant about this little bolt. That's cool. Found this on the way to Archive War.
thanks,

1st of 4 benchmarks this evening. I visited with The Queen of Everything. We missed this one the last time we were here. I'm sure we saw it, but didn't take a picture.

#99 Visiting Austin for the NTGA Road Trip and the Austin Halloween Bash event caches. This was my first bolt mark to find.

Found this in the rain with my sons on our 18 cache ( most of them virtuals ) day. I love the looks the DPS officers give you while you hunt for these things.

Control Text

  • The horizontal coordinates were scaled from a topographic map and have an estimated accuracy of +/- 6 seconds.
  • The orthometric height was determined by differential leveling and adjusted by the National Geodetic Survey in June 1991.
  • The geoid height was determined by GEOID99.
  • The dynamic height is computed by dividing the NAVD 88 geopotential number by the normal gravity value computed on the Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45 degrees latitude (G = 980.6199 gals.).
  • The modeled gravity was interpolated from observed gravity values.
