The Wolf came to visit and wanted to do some caching. We originally planned some power trails but he was really wanting to grab Mingo. What the heck I guess we can do some targeted caching for a few days around that. We left Austin at the crack of dawn ready for some action. This will be a fun trip leading up to next month's Nevada trip for some numbers and then the Arizona trip for a ton of GeoArt at the end of the year. What a great ending to a great year filled with new adventures. Thanks to all the COs who placed and maintain these caches for us to enjoy. I will be sending the answers for any caches that require them for the both of us by the end of the night when back at the hotel. Thanks!!

Control Text

  • The horizontal coordinates were scaled from a topographic map and have an estimated accuracy of +/- 6 seconds.
  • The orthometric height was determined by differential leveling and adjusted by the National Geodetic Survey in June 1991.
  • The geoid height was determined by GEOID99.
  • The dynamic height is computed by dividing the NAVD 88 geopotential number by the normal gravity value computed on the Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45 degrees latitude (g = 980.6199 gals.).
  • The modeled gravity was interpolated from observed gravity values.
