A few words about benchmarks. We may never have to search them again, but just in case...
Let's follow in Chateau's footsteps. First, go to this page
for some general reading. At the top of the page you'll notice a couple of search boxes: one for zip code and one for Point ID. The zip code for White Water is easily found--92282--and when entered yields 460 hits. Too many, we need to map them out. Click on the button top-right and download the whole set as a loc
file. Open Google Earth, click File>Open and point it to the loc file you just saved (the default for Google Earth is kmz/kml, so you may need to change the file type in the dropdown box at the bottom of the window). The cap below is what you get. Since we already know the general area, we can narrow it down: DX1061 looks like a good candidate. Go back to the Geocaching page and put DX1061 into the PID field; open it up to find a comment by you-know-who. To double-check, click "view original datasheet" and you can verify that the benchmark matches Chateau's find and not the other posters/geocachers.
Thank you Chateau for your field trip, it looked like fun
