Found this during our lovely morning hike.

Noticed this as we were taking pictures of flowers on the road east of the Holei Sea Arch. Fun discovery!

Saw this on our walk on the road to nowhere today. We took the Chain of Craters road to the end and saw the sea arch and walked the closed part of the emergency road. Saw this BM on our way back to the car.

Found by accident while at Volcanoes NP.

Recovered in good condition following the description more than the coordinates which for some reason put me on the wrong side of the road, might have entered them incorrectly.

Found on the walk to the lava flow blocking the road. Spent the day exploring Volcanoes National Park. No vacation is complete without finding something... 5,000 miles from home

Found benchmark while hiking w/ wife to see the steam plume from the active lava tube.

It's nice that the arrow on the roadway points right to it.

On our way to the end of the road

Walking out to visit the Hot Rox virtual cache and passed by this.

Ha ha, just got around to logging this. It has been sitting in my GPS for two years! I found this by accident and I DO have a picture. There is another one nearby that I also found.

Found it on the way to lava night show with TCWprez

Found it on the way to see the lava flows at night. Tipped off by the BM and arrow in the road.

Found after a rather long and very warm hike out to the "Hot Rox" cache! Thanks to dblbck for spotting this marker!

We were also tipped off by the BM and arrow on the road. First BM we have actually found and logged. We were both soaked to the skin from rain (and the only rain we encountered on the big island for 2 weeks). Did not see the lava, save the steam rising from the ocean. Enjoyed the park though.

On the Big Island with Wife, on vacation. Spent the day exploring Hawaii Volcanos National Park and found chalk mark on the pavement near end of Chain of Craters Road. Looked it up when we returned home (Pennsylvania), Wife thinks I'm some-what nuts. Had a great time!

Documented History (by the NGS)

01/01/1978 by USGS (MONUMENTED)
DESCRIBED BY US GEOLOGICAL SURVEY 1978 (LAC) THE STATION IS LOCATED ABOUT 8 MILES SOUTHWEST OF KALAPANA VILLAGE AND IS IN THE VOLCANO NATIONAL PARK. TO REACH THE STATION FROM THE TWO CHURCHES AT KALAPANA VILLAGE, GO SOUTHWEST ON STATE HIGHWAY 13 FOR 2.8 MILES TO A GUARDRAIL AT END OF THE STATE HIGHWAY. CONTINUE SOUTHWEST ON THE PAVED ROAD FOR 4.7 MILES TO STATION LAEAPUKI TURN-OFF. CONTINUE SOUTHWEST ON THE PAVED ROAD FOR 0.55 MILE TO THE STATION ON THE RIGHT. THE STATION MARK IS A USGS DISK STAMPED HVO 80 1965, CEMENTED IN A DRILL HOLE IN AN OUTCROPPING OF LAVA ROCK THAT PROJECTS ABOUT 1-1/2 FEET ABOVE THE SURFACE OF THE GROUND. IT IS 20 FEET NORTHWEST OF THE CENTER OF THE PAVED ROAD, 4 FEET SOUTHWEST OF A 2 FOOT CAIRN, 11 FEET SOUTHEAST OF THE SOUTHEAST EDGE OF AN 8 FOOT HIGH LAVA MOUND AND IS ABOUT 1 FOOT HIGHER THAN THE PAVED ROAD.

Control Text

  • The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in December 1998. 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. The vertical network tie was performed by a horz. field party for horz. obs reductions. Reset procedures were used to establish the elevation.
  • The Laplace correction was computed from DEFLEC99 derived deflections.
  • The geoid height was determined by GEOID99.
