The cache is not at the posted coordinates. This regular-sized container is at N 34 AB.CDE W 119 FG.HIJ Each of the 33 physcial caches in the OVC GeoArt Project contain a letter and number key to obtain the final coordinates. You do not need to find all of the GeoArt containers to be able to claim the bonus.
Although 28 of the geocaching on in the OVC GeoArt Project are Park and Grabs, five are not. To get all caches will require approximately one mile of easy hiking. To claim the Bonus Cache, one needs only hike .1 mile, however the trail is steep and one must watch carefully to stay on the trail.
Good luck.
