Ascent Trip Report

In July, 2013, Roger Kaul and I summited Mount Lamlam - or so we thought. This year we returned (as part of our expedition to Agrihan) with a real-time kinematics GPS system to definitively determine where the highest point is located.

The trail has been greatly improved over the years. It's an easy-to-follow trail to the Flagpole. The only concern being where to cut up to reach the false HP (flagpole). Continuing on it was very useful to have NateB's GPX track with us. There is a lot of flagging and paths immediately after the flagpole turn-off. Eventually you'll make your way through the forest and onto the ridge which leads to the true highpoint.

The GPX track I've uploaded starts at the true HP (note, not at the end of NateB's track) and returns to the trailhead. It eliminates a lot of the "wandering" around in the woods and has the extension to the crosses on Jumullong Manglo.

Roger and I placed the base station next to the benchmark on the concrete slab at the false summit. We then took the rover and measured the flagpole as well as several points along the ridge with the true highpoint. Relative measurements are:
Flagpole = 1.1879m higher
South Point = 6.3885m higher (409.631m/1344ft MSL)
North Point = 6.3202m higher
NateB endpoint = 5.6443m higher

The "South Point" is at 13.33974, 144.66562 and is tagged with some orange flagging and is where my GPX track starts. The "North Point" (further from the flagpole) is about 8 feet away. Given they are ~6.7cm/2.6in different, I would recommend touching both. The error is +/- 1cm but still ... The altitude of 1344ft seems high (versus USGS of 1332ft), but we didn't have time to do a long survey-in to get an accurate absolute value. We were primarily interested in relative heights.

Unfortunately, Roger and I forgot to bring a summit register (and Jack Longacre's ashes). We gave these to David Darby and Rob Suero who came the next day (see David Darby's TR). Looking at video evidence, it appears David and Rob placed the summit register (peanut butter container) at the NateB endpoint, not the true highpoint (South Point) we flagged ;( If someone can bring it back and place it correctly, it would be greatly appreciated.
