What a beautiful walk across the valley

The coordinates were quite accurate for this one. The West Side Road was closed due to recent flood damage, we had to walk across from the Badwater Parking Area. Thanks, Fort Rectus
Our first Gravity Station.

DustyKat was the one to point out this benchmark and how rare this type is. Very cool to find!

How cool to find this rare type of Benchmark! All is good here.

Recovered as described. In good condition. This is a very rare type of benchmark.

Visiting from Ohio with Dame Deco. We enjoyed caching and finding this rare benchmark in Death Valley.
It's in great shape.

This rare disk was one of the reasons I made a caching trip to the region with skibug9 this week. It was a thrill to recover it in good condition! Rough drive out, saw a coyote on way back--he ruled the road for a bit, and we respectfully followed!

As noted in earlier recovery logs there is a ring of stones around the mark to help reduce erosion of the concrete. My first gravity station disk and what a remarkable location!

CHECK OUT GC5C2E3, the South Florida Benchmark Challenge.

Woohoo, I've had this one on my list for some time now.
We're in the area from S. Florida to make this journey from LAS to Death Vallley to visit this Gravity Station; very cool.
Entered gravel road from the south and continued past this station exiting at the north end. A hot and bumpy ride.

Alrighty now 2nd one of the day
Another great location

That happens when its not on correct settings.

Found in fine condition, as described. Also found to be great fun.

Bench mark is in place. Someone has stacked rocks around the base to slow down the effects of wind erosion.

Took a few days off from work to take a power benchmarking vacation. Found this mark right where it was supposed to be. This was the 89th of 105 marks found over a three-day period and the 35th and final on this 3rd day (2nd full day as day 1 was a 1/2 day). The mark is in good condition and solid, but the concrete around it has eroded to the point that the edges of the marker disk extend beyond the remaining concrete. The setting of this mark is in need of urgent repair. Recovered the azimuth mark in good condition. There are no longer witness posts at either the station or the azimuth mark.

Found in good condition. It's the first gravity station disk I've found.

Found this unusual and possibly lowest station in the U.S. in good condition. The concrete is deteriorated, but the mark is solid in the setting.

This station is on the east side of the West Side Road and south of the Dayton Harris gravesite.

The Azimuth mark is approximately 0.26 miles south and on the opposite side of the road, this mark is on a small rise and is in good condition.

Found this while taking a long drive on the

My first Gravity Station. Looks to be in good
shape. Note the elevation on the GPS.

Documented History (by the NGS)

01/01/1950 by CGS (MONUMENTED)
DESCRIBED BY COAST AND GEODETIC SURVEY 1950 (RJS) THE STATION IS LOCATED IN DEATH VALLEY ABOUT 26 MILES WEST-SOUTHWEST OF DEATH VALLEY JUNCTION, ABOUT 18 MILES SOUTH OF FURNACE CREEK, ABOUT 200 FEET EAST OF THE ROAD BETWEEN FURNACE CREEK AND BENNETTS WELL AND 19 FEET EAST OF A WHITE WITNESS POST. THE STATION WAS REINFORCED WITH ADDITIONAL CONCRETE BECAUSE THE ORIGINAL CONCRETE APPEARED TO BE DETERIORATING. IT WAS NOT MOVED HORIZONTALLY OR VERTICALLY. THE STATION MARK IS A U.S. COAST AND GEODETIC SURVEY STANDARD BRONZE GRAVITY STATION DISK SET IN A 12X12 INCH CONCRETE POST, PROJECTING 5 INCHES. IT IS STAMPED DAYTON HARRIS 1939. THERE WERE NO REFERENCE MARKS ESTABLISHED AT THIS STATION. THE DAYTON-HARRIS GRAVE MONUMENT IS A RECTANGULAR CAIRN WITH A 5X6 FOOT BASE. IT IS ABOUT 6 FEET HIGH. ON THE WEST SIDE OF THE CAIRN THERE IS A BRONZE PLAQUE DEDICATED TO THE TWO PIONEERS BURIED AT ITS BASE. THE POINT INTERSECTED ON THE CAIRN WAS THE CENTER OF A 1X4 THAT IS APPARENTLY THE TOP AND CENTER OF THE CAIRN. THE AZIMUTH MARK IS LOCATED ON THE TOP OF A SMALL RISE OF GROUND WHICH IS ABOUT 5 FEET HIGHER THAN THE SURROUNDING COUNTRY. THE MARK IS 31 PACES WEST OF THE CENTER OF A GRADED ROAD AND 6 FEET SOUTHEAST OF A WHITE WITNESS POST. IT PROJECTS 3 INCHES AND IS STAMPED DAYTON HARRIS 1950. TO REACH THE STATION FROM THE ROAD JUNCTION 0.1 MILE WEST OF THE ENTRANCE TO THE FURNACE CREEK INN, GO SOUTH ON A PAVED ROAD FOR 5.8 MILES TO A FORK AND SIGN DEVILS GOLF COURSE, BENNETTS WELL. TURN RIGHT AND FOLLOW THE MAIN GRADED ROAD FOR 12.2 MILES TO THE STATION ON THE LEFT (EAST). A DRIVE STATION. TO REACH THE AZIMUTH MARK FROM THE STATION, GO SOUTH ON THE GRADED ROAD FOR 0.25 MILES TO THE AZIMUTH ON THE RIGHT (WEST) AS DESCRIBED ABOVE.
01/01/1943 by NGS (GOOD)
RECOVERY NOTE BY NATIONAL GEODETIC SURVEY 1943 17.8 MI S FROM FURNACE CREEK INN. 17.85 MILES SOUTH ALONG THE SHOSHONE ROAD (VIA BENNETTS WELL) FROM FURNACE CREEK INN, ABOUT 200 FEET EAST OF THE CENTERLINE OF THE ROAD, AND NEAR THE MONUMENT DEDICATED TO JAMES DAYTON AND SHORTY (FRANK) HARRIS, PIONEER GOLD SEEKERS IN DEATH VALLEY. SET IN A CONCRETE POST.
01/01/1967 by LOCENG (GOOD)
RECOVERY NOTE BY LOCAL ENGINEER (INDIVIDUAL OR FIRM) 1967 RECOVERED IN GOOD CONDITION.
01/01/1969 by CGS (GOOD)
RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1969 (WFF) THE STATION WAS RECOVERED AS DESCRIBED AND WAS FOUND TO BE IN GOOD CONDITION. THE DESCRIPTION TO REACH THE STATION IS COMPLETE AND ADEQUATE. IT SHOULD BE NOTED HOWEVER THAT THE ELEVATION OF THE MARK IS NOT 256.7 FEET BUT MINUS 256.7 FEET BELOW SEALEVEL. AIRLINE DISTANCE AND DIRECTION FROM NEAREST TOWN--THE STATION IS ABOUT 26 MILES WEST-SOUTHWEST OF DEATH VALLEY JUNCTION, AND ABOUT 18 MILES SOUTH OF FURNACE CREEK

Control Text

  • The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in March 1994. The horizontal coordinates are valid at the epoch date displayed above. The epoch date for horizontal control is a decimal equivalence of Year/Month/Day.
  • The orthometric height was determined by differential leveling and adjusted by the National Geodetic Survey in June 1991.
  • The Laplace correction was computed from DEFLEC99 derived deflections.
  • 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.
