While perusing some geocaching blogs today, I ran across Desert Woodrat's Weblog. In his post, Heart of the Desert, he describes a series of geocaches that are in the shape of a heart! Here's a screen shot showing the geocaches.
I know what you're thinking.
Someone Photoshopped the caches onto the picture?
Click on the photo and the link will take you to the Geocaching web page. The caches are located northwest of Moab, Utah.
I encourage you to visit Desert Woodrat's Weblog. Do some clicking around there. Many, many excellent desert photos, including some cool petroglyphs. Excellent site.
