While exploring south eastern Utah, I made a stop at the well-published Head of Sinbad pictograph site. This impressive site is a worthy representation of the Barrier Canyon culture style of pictographs dating back nearly 3,000 years. Today one of the main panels is slowly being covered by sediment being washed down the cliff face from high above and will someday in the future completely cover this panel.
The same summer thunderstorms causing the sediment flows can also cause havoc on access to the site; during my visit in the summer of 2007, 4×4 and decent clearance was required to transverse the rutted and eroded road(s) to the site – though not always the case. If you happen upon this site in your travels, as with all sites, please respect it and take only photos!
