11-Oct-2018 -- Once again we made the trip to the USA to attend the 2018 ASA annual meeting in San Francisco where we were to present results of our team.
This time I had a week of vacation before the meeting and we decided to visit Texas and especially the Big Bend and Carlsbad National Parks and White sands National Monument. After the meeting we spend 3 more days of vacation in Santa Cruz and the bay area.
We successively visited N32 W104, N3 W 106, N37 W122, and N38 W123 during that trip as there were points easy to reach from a road.
All these visits were made with a poor precision because the screen of my GPS receiver was broken during the flight and the device was completely useless at arrival. I decided to keep the visits on our schedule but I used my cell phone compass which of course wouldn’t offer the precision to zero in the points.
Comparing the previous visits to each of these points and the Google earth pictures along with the coordinate read on my phone and the actual pictures I shot, I am pretty sure that all 4 visits were made within the 100 meters limit to allow validation of the visit. Nevertheless, as I was unable to zero any of the points, I submitted the 4 visits with a 99 meters precision.
N33 W106 is located 12 km north of Alamogordo NM and is easy to reach by car. We parked on the shoulder of Riata road west of the railway and walked to the point through the red sands and bushes. We crossed the railway by walking beneath the railway bridge that can be found at approximately 110 meters south west of the point. No one was out on that late afternoon and we only encountered a little black spider.
