When you are walking on the top of Half Dome, one thing you may notice is that there is no survey marker. While on the summit of many other peaks and high points you often see the 4-inch bronze disks cemented into the rock. The photo below shows the marker on Clouds Rest.
So why no marker on Half Dome? The reason is simple: there was no reason to put one there! These markers were placed by either the U.S. Coast and Geodetic Survey (now called the National Geodetic Survey), or the U.S. Geological Survey (USGS), to aid in survey work leading to the creation of maps of the terrain. When reading survey makers, you will notice that the information may vary. You might find a triangulation station, or the “main station.” It is marked with a triangle inscribed on its surface and an impressed mark that shows the precise point over which a surveyor’s plumb should be placed. A triangulation station is often bracketed by two reference markers with arrows pointing to the main station. Just because Half Dome is a high mountain, does not mean it gets a survey marker. Other peaks provide the data needed by the engineers. Yosemite Point, Mt. Hoffman, El Cap, Sentinel Dome, etc. have markers. So save your energy and just enjoy the view.
Medical update: I got released from Good Sam hospital today. The pleural effusion was a success. I had all the gear pulled out of off me. Chest Tube, epidural, IV, med port, EKG leads and of course, my favorite: the catheter. Owwwww. The procedure was a success and I feel a lot better. My side has 4 healing holes in it and they are starting to glow.
