1047: Found with AZ Star Splitter. We approached from ET0317 and found a track road leading to the base of the hill. From there we hiked up the western face of the hill to the summit & Mark. Although there is no trail, there is plenty of open area to make a relativly easy hike.

Mark was within 8 ft of GZ and elevation recorded at mark was 4253 feet. As AZ Star Splitter noted, the reference marks were not found. Elevation diffenece from ET0317 is 203 feet.

The View from the summit to the east made the climb worth the effort.

will Post Pics soon

View looking southeast from the top of Estler Peak. Note the eagle soaring in the upper left of photo!

Didn't go looking for this one but saw it after climbig to the top. Originally we planned to hike in the Cedar Bench Wilderness but ran into a long stretch of deep mud that brought us to a stop. Fortunately, we were on a slight uphill grade and even though we couldn't go forward because we were dragging the underside in the mud we were able to get free and back up about a hundred yards to a point where we could turn around. On the way back we decided to climb to the top of Estler Peak and found this triangulation point. Fantastic views from the peak.

The peak that caught our attention. Later we learned it's named Estler Peak.

Notice the grass surrounding the triangulation point. This has been a wet winter and the desert has turned green. The flowers, butterflies, birds, clouds, sun and breeze made it a perfect day.

01/01/1959 by CGS (MONUMENTED)
DESCRIBED BY COAST AND GEODETIC SURVEY 1959 (SLH) THE STATION IS LOCATED ON THE HIGHEST POINT OF A VERY ROUGH AND ROCKY HILL THAT IS 6 MILES NORTHEAST OF CORDES JUNCTION, 3 MILES NORTHWEST OF DUGAS, 0.5 MILE SOUTH OF A POWERLINE AND JUST NORTH OF SPRING CREEK. TO REACH THE STATION FROM CORDES JUNCTION, GO NORTH ON STATE HIGHWAY 79 FOR 6.1 MILES TO A CROSSROAD AND SIGN ON THE RIGHT, DUGAS-SYCAMORE STA. TURN RIGHT AS PER SIGN AND GO EAST ON THE BLADED ROAD FOR 0.4 MILE TO A Y-FORK, TAKE THE LEFT FORK AND CONTINUE EAST ON THE BLADED ROAD FOR 2.0 MILES (THIS IS 0.3 MILE BEFORE REACHING A POWERLINE). HERE TURN RIGHT AND GO ACROSS COUNTRY FOR 0.2 MILE TO THE BASE OF THE HILL. FROM HERE PACK EASTERLY UPHILL FOR ABOUT 10 MINUTES TO THE HIGHEST POINT OF THE HILL AND THE STATION. THE STATION MARK, STAMPED SPRING 1958, IS A STANDARD DISK CEMENTED IN A DRILL HOLE IN A BOULDER THAT PROJECTS 6 INCHES AND IS 11.5 FEET NORTHEAST OF A WITNESS POST.

Control Text

  • The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in August 1993.
  • The NAVD 88 height was computed by applying the VERTCON shift value to the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
  • The Laplace correction was computed from DEFLEC99 derived deflections.
  • The geoid height was determined by GEOID99.
