You can HELP BUILD SELECTION when you become a MARKER SLEUTH™!
Our goal is to produce authentic replicas of actual markers at America's favorite sites and summits. Help us expand the SummitMark™ and SiteMark™ collections by becoming a member of our elite team of MARKER SLEUTHS™. (See our Most Wanted List and Markers on Deck)
When you hike, climb, or visit a geographically significant site, look around for survey markers. Take a photograph of markers you find. It's challenging and fun and the marker(s) you locate could become part of the collection. If a submission results in a new product, you or your organization will be credited for the contribution on the back of that product's informational hang tag. You will receive one each of the products developed from your submission, as they become available. Generally we will produce pins, zipperpull/pendants and paperweights.
You will be more successful when you prepare. Use our site to find official survey data sheets to find the markers. Here are the steps to take:
- If the site you are planning to hike or climb is on our Most Wanted List, record the coordinates listed there and proceed to Step 3.
- If not, go to http://geonames.usgs.gov/pls/gnis/web_query.gnis_web_query_form (Geographic Names Information System) to find the coordinates of the site (Enter place name, state, and geographic feature; EX. Whitney, CA, Summit)
- If not, go to http://www.ngs.noaa.gov/cgi-bin/ds_radius.prl and enter the coordinates. Follow directions to format Lat/Lon; Choose ANY HORIZONTAL/VERTICAL CONTROL, and a radius of 1 mile. (Bench marks and Triangulation station marks are preferred over reference marks. Note: reference marks have arrows on them pointing in the direction of the preferred mark.)
