A good day

I think I'm done with this run. Wish that I had lots of time down here to check for more of the NONPID's that have fair descriptions in Sp Pub #18. kayakbird

Interesting area - just west of this station, you can see not two, not three, but *four* generations of US66. In order of age (newest to oldest): I40, The old paved route (curves northward to exit on I40 and crosses over), an older, possibly cement route heads straight and curves up more slowly, and finally the old dirt route, where the previous curved more westward this one made a more sharp turn right after crossing I40.

 

Darn neat. ;)

What is Sp Pub #18?

The Special Publications in general are a series of reports that go back to then 19th Century which detail special accomplishments of the CGS formerly the CS. These supplement and go well beyond the Annual Reports published by the agency. For us they are nothing less than a Treasure Trove of historical information.

 

SP 18, is entitled "FOURTH GENERAL ADJUSTMENT OF THE PRECISE LEVEL NET IN THE UNITED STATES AND THE RESULTING STANDARD ELEVATIONS" published in 1914. It is what it says and I suggest you take a look at it,

 

The Special Publications have been digitized and are available Here

This past Friday started out very frosty at the Pearce Ferry campground and an extra cup of coffee and a visit with the only neighbor

I'd had in week put me two hours late at South Cove for a launch to the mouth of Hualapai Wash. By the end of a windless,

55 F day I had managed to log nine marks to close the gap left in the Wash last spring, observed the aftermath of a massive flash flood last summer and

enjoyed a well after dark six mile paddle back to South Cove.

 

And of course, came up with an unsolved mystery.

 

This one FS0409

 

cbf21ca2-c9f9-48fc-908b-e412f43d6248.jpg

 

may have been uncovered this year, the upstream end shows a lot of abrading from bedload; but I don't think that it got moved 1000 ft upstream.

It was found at the published L/L for FS0831, which remains NOT FOUND. But is B 129 on a rock or a post?

 

FS0831'WASH, 38 FEET EAST OF THE CENTERLINE OF THE ROAD, IN TOP OF NORTH

FS0831'ROCK OF TWO LARGE ROCKS ON EAST BANK OF WASH. A STANDARD DISK,

FS0831'STAMPED B 129 1935 AND SET IN THE TOP OF A CONCRETE POST.

I did not have time to carefully search all the pairs of of large rocks along several hundred yards here but I think that there is a good chance that this one and other

NOT FOUND's along Hualapai Wash are still there. Several of the FOUNDS were hundreds of feet up wash from the published L/L. Generally the calls are very good.

 

Trees have grown up after 75 years.

I really enjoy reading about these kinds of journeys & seeing the accompanying photos.

A photo or two (or more) of the paddle approach to the Wash would be pretty fun to see... and not off topic!

NorthWes & all,

 

This shot was taken last February looking up reservoir (northeast). Hualapai Island - now a peninsula - is just across Hualapai Wash

which now extends just over a mile southeast before it hits gravel. South Cove is on photo right in the distance, reservoir ends three miles north of there

and there are now two Class IV rapids after the Colorado River exits Iceberg Canyon, the notch on the horizon.

 

The reservoir was flat and all mine that night but I decided to keep the shore close

to my right shoulder - must have gone in and out of 500 tiny coves.

From the Nevada side of the reservoir, again looking NE. Not always that tranquil!

Why do they only have up through 1965?

 

In 1965 the US Coast & Geodetic Survey became part of the new ESSA (Environmental Science Services Administration), so I'm guessing that had something to do with the Annual Reports ending. Note, in 1970, ESSA and other organizations were combined to create NOAA.

Actually a good week once I finally gave up all hope of getting into the Missouri Breaks for a kayak camping, MORC hunting trip this monsoon season and decided that I may as well work on the multitude of Cold War era missile site associated bench marks in Fergus Co, Montana. Had a three day string where I found, in good condition, every one of the 54 that I looked for.

 

A bit amazing considering that six are in the midst of a current road improvement project on MT 81.

SR0694

 

MTDOT did help out quite a bit within the construction zone and another ten miles or so further west with lots of fresh lath and flagging. Even several with evidence of a recent tripod occupation.

SR0710 Yes, Virginia, scaled bench marks are still important! It will be interesting to see if MTDOT submits HH1 or better Lat/Longs.

As I've found most of the Geocaches around my area I've turned to finding benchmarks.

 

I was quite surprised to have first log on a couple of finds yesterday evening.

Welcome to benchmarking. I'm just down the road in San Luis Obispo county.. There are a few marks up there in your neck of the woods that I've been eye-ing but I haven't made it up there yet.... their orthometric height is within a meter of the geoid height.

Had my eye on Mulligan Hill at the mouth of the Salinas River for a while. Friday after work I hiked the 2 miles down the beach and up to the hill along the river.

 

About 5 miles hiking in sand, which is great for the quads. Oooph.

First found Reference Mark 2

Then MULLIGAN

Then Reference Mark 1

All pretty easy, considering.
