I spotted this one with a few others very close by. As if hiking to the top of the highest mountain in the lower 48 wasn't enough.

Found this BM on a successful summit hike.

Rewarded on this hike with a somewhat challenged BM and the greatest views from the top of the contiguous United States.

I'm going with the preponderance of the evidence and logging this as a find. I can just make out "502" stamped on the disk to the left of the lower cross line adjacent to the "FEET" and "B" right of that line.

Found with shell1fish and NakoTakoPatrol. She attached pics. What an amazing adventure.

This one's pretty badly damaged. Lightning, perhaps?

benh57, NakoTacoPatrol, and I hiked Mount Whitney in one day, and we were thrilled to make it to the top around noon. The 14502 benchmark is the highest one we saw in the cluster of several on the tops of boulders at the summit. The aluminum disk is badly damaged, with half of it missing and the remainder heavily scratched.

pretty beat up but i think this is the one

Aloha! As with the several other benchmarks logged, what better way could a hiker end a John Muir Trail thru hike (Yosemite to Sierras) than by summitting Mt Whitney... on Sept 11th at that! What a fantastic adventure and way to end! Add in several benchmarks and a couple of caches and you have the flame to the candle on the birthday cake. AWESOME! Loved the adventure. On to the next! Aloha!

Saw this at the peak!! Hiked up from Whitney Portal via the trail. 6hrs up & 3hrs 40min back down!

First time summiting...

Made the Journey to the peak for a second time. The most incredible views can be had from this location on the right day. Today the weather was perfect!

I ascended Mount Whitney and reached the summit at approximately 1:00 pm on this day.

Most of it is still there but it has seen better days.

This one is busted and scratched to hell. The only reason I could ID it is from everyone else's photos from prior finds.

Great view from the summit.

Awesome--two caches atop Mt. Whitney, and benchmarks too. What a great trip, our first time here.

Wow, this was one tough hike. My friends and I spent the night at Trail Camp and then summitted on this Saturday. We had hoped to downhike all the way down on the same day, but we were so bushed that we stayed at Trail Camp another night. A wise decision it turned out.
On the summit, all I wanted to do was go back down. I was feeling horrible, headache and breathing hard. I got some real cursory pictures, signed the log and looked at a couple of the benchmarks. Before heading down; I looked for the physical geocache up here; but only give it a minute and a half or so and retreated to lower elevations.

At first, I didn't think I'd found this mark. After looking at another picture, I can just make out the 502 of 14502 in the left lower quadrant of the plus sign like hashes in the middle of the disk (that's gotta have a real name).
That and a aluminum disk get me to call this a find after all.
I'm pretty sure the cement or epoxy below it was for the original plaque.

Here's what I saw.

This is one of several BM's on Mt. Whitney. We were wandering which one actually was the highest point of the summit, it was not readily obvious. This, I believe, was the only aluminum disk. Unfortunately, no pictures were taken. We summited around noon from Trail Camp.

Documented History (by the NGS)

1/1/1962 by CGS (MONUMENTED)
DESCRIBED BY COAST AND GEODETIC SURVEY 1962 (JCC) THE STATION IS ON THE HIGHEST PART OF MOUNT WHITNEY, 16-1/2 MILES SOUTH-SOUTHWEST OF INDEPENDENCE AND 13 MILES WEST OF LONE PINE. THE MARK IS A UNITED STATES GEOLOGICAL SURVEY ALUMINUM DISK, STAMPED 14502, CEMENTED IN A DRILL HOLE IN A 5 BY 10 FOOT BOULDER PROJECTING 3-1/2 FEET. A TRAVERSE CONNECTION WAS MADE TO TRIANGULATION STATION WHITNEY 1950, THE DISTANCE BEING 9.78 FEET OR 2.982 METERS NORTH OF THE STATION.

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 scaled from a topographic map.
  • The Laplace correction was computed from DEFLEC99 derived deflections.
  • The geoid height was determined by GEOID99.
