Geocache Description:

6th P.M. 150th Anniversary event Saturday, June 10, 2006 - 9:00 a.m. to 3:00 p.m. at the Kansas-Nebraska border.
Coordinates: North 40o 00’ 07.1” Latitude West 97o 22’ 09.1” Longitude .

KSLS LogoThis is an opportunity for geocachers to see "where it all came from" for Kansas, Nebraska, and parts of South Dakota, Wyoming and Colorado, and for surveyors to see what kind of geocaching fun they can have using GPS. Surveyors are invited. Geocachers are invited. There is no charge for learning about the history. (Surveyors have to pay money if they want to get continuing education credit out of this deal.)

CITO ImageThe festivities will start at 9AM at the above coordinates with speeches about history and the commencement of some surveying games. Show up early for good parking. This is where the TRASH OUT part comes. Geocachers can show off the environmental awareness common in geocaching by cleaning the area around this monument that is significant to the surveying community. The geocaching will start at about 10AM in the town of Mahaska which is one mile south and one mile east of the above coordinates. Roads are better in town. This way, if it rains, the geocaching can still go on intown, and you don't have to worry so much about muddy roads. Plan on explaining what geocaching is "really like" to the surveyors; bring your best adventure stories (or horror stories). I'm sure the surveyors will show off their stuff, too, with old measuring devices and high-tech super GPS stuff. Don't forget your cameras and bottles of water!

KSLS is planning the following:

  • KSLS (Cam Howell) will have a chaining crew re-enactment at the site.
  • The Oregon Trail Association will provide wagons and horses for color.
  • Pony Express reenactment with an actual mail handoff.
  • Short speeches and observe the site---travel to Mahaska, KS
  • GeoCaching will be encouraged in the immediate area.
  • Lunch at the community center (local church is preparing so approximate numbers will be needed) $7.50 Send reservation to Lunch may also be purchased the day of the event.
  • Surprise visit from Surveyor General John Calhoun, circa 1856.
  • Steve Brosemer and Jerry Penry will have a 1.5 hr history of the 6th P.M. and the Baseline.
  • Surveying information booth with monument stone, old to new equipment, other items of historical surveying interest.

POB Magazine sent an announcement in early March about the event and the states involved. We are also planning on sending pictures and a brief story of the event after the fact.


KSLS will be hiding these little notes around Mahaska. Coordinates will be available for these hides. These particular hides will be event-only geocaches. Find a note and see that it tells you that you are entitled to have one Sacagawea Gold Dollar. Find me and show me the note. I'll give you the gold dollar. There will be fifty notes for fifty gold dollars. I'm going to wear a ball-cap with a KSLS logo on it, as well as this annoyingly bright green t-shirt with a big blue CITO logo on the front. I'll have my "REMEMBER" message on the back. 50 dollars, one dollar at a time!

At 10:00 I’ll be at the Mahaska park, 1 block south of Main and Highway Avenue.

Other geocaches are also encouraged. Be sure to follow all the regular rules for submitting geocaches. Be sure it is in an area close enough for you that is maintainable and not too distant from home. Geocaches like these are still going to be available for searching after the events are over.

Around 11:15, we’ll all meet at the park and enjoy the sharings of the geocoin horde. Then we’ll start to wander up to the Community Center for lunch and be ready for the show by 12:30. The Community Center is one and a half blocks north of Main and Highway Avenue. Parking will be available along Main Street.

Mahaska City Hall said that trash bags can be disposed of at a trash bin that will be on the south side of the Community Center. I'm going to bring lots of little film canisters with trash bags stuffed inside, to hand out at the event to promote the CITO policing of the area.

Also look up a geocache in this area. Waypoint GCPH8J by jayhawk-eyedoc & jhawkmommy.

While on your geocaching adventures, REMEMBER

  • Make the fair trade.
  • Log your visit.
  • Leave the site better than you found it.
  • Protect the environment — always.
  • Educate those around you.
  • Find another cache!

Good luck, and may all your cache dreams come true.
