The Rochester Creek rock art panel near Emery, Utah consists of mostly petroglyphs, some in the Fremont style (700-1300 AD). The Fremont culture was contemporaneous with the Anasazi.

This panel clearly has some Fremont petroglyphs as well as more modern "rock art and grafitti". Ute Indians may have produced some. A few experts feel there are some much older Barrier Canyon style figures at this location.

Basics: Petroglyphs were "pecked" into a rock surface. Pictographs were "painted" onto a rock surface.

Some of the pictographs found in Utah are over 3,000 years old. The paint the native American used to make many of the Colorado Plateau pictographs consisted of ground hematite mixed with animal fat and and bird eggs. The paint was absorbed into the sandstone matrix and when protected from the elements (and morons - modern vandals); have lasted thousands of years.

Dating petroglyphs can be tricky, even for trained scientists, who many times must depend on "style" and other clues associated with the rock art to date the rock art. Pictographs have the advantage of having organic materials used in their creation, which may aid dating.

NOTE: If you have a deep interest in rock art (pictographs and petroglyphs) of the American Southwest then get the excellent book titled: "Legacy on Stone" by Sally J. Cole. This is not "page turner" reading and gets pretty technical at times, but if you want some well researched facts and information on the rock art and their presumed creators, then get her book.

We drove through the night from our home in Eastern Washington to downtown - - Emery, Utah.

I always fill up with gas whenever wandering around back country roads, so I stopped at Emery to fill up our pickup truck and to ask some questions about the points of interest we wanted to visit. I have heard that some men don't like asking for directions or information, but I'm not one of them. I learn a LOT from asking local folks, who know the area, for the latest hiking, sight seeing, and travel information.

I met a really nice couple, who ran the small store and gas station at Emery. They confirmed our planned travel plans to reach the trailhead for the Rochester Creek rock art panel hike.

I casually asked about how rough the road might be from Moore to I-70 (Called the Moore Cutoff Road locally), and was astonished to hear that it was now paved and you could whisk along at 55 mph. This was good news, since the Head of Sinbad rock art panel was going to be our next destination that afternoon. It was also where we hoped we could "car camp".

The couple handed me a pamphet titled: "San Rafael Country" which had a nice map, photos, and up to date information on the points of interest in the area. See: [www.sanrafaelcountry.com]

We welcomed the warm weather to hike in and we both enjoyed the hike and the pictographs and petroglyphs of the area. It is always fun to try to get inside the mind of the "artist" who created the rock art, hundreds and many cases, thousands, of years ago.

Road Trip - Utah April 17th - 24th, 2010: My wife and I headed for Southern Utah, just before midnight on Friday the 16th of April (after she got off work at her part time job). We drove straight through to Southern Utah, to take advantage of the good weather forecast early on in our trip. Storms were forecast for later in the trip and in fact we got a pretty good taste of same on Wednesday the 21st.

Here in outline form are the places we visited and hiked:

Saturday 4.17.2010
> Rochester Rock Art Panel near Emery, Utah
> The Moore cutoff road
> Sinbad’s head pictograph panel (we camped under a pinon pine near here)

Sunday 4.18.2010
> Black Dragon Canyon rock art panel (after first taking the wrong turn and doing some interesting four wheel drive travel way up the San Rafael River). Short hike.
> Pictograph Canyon pictographs. Short but interesting hike.
> Drive Hanksville, Torrey, Boulder, to Escalante (check into motel)

Monday 4.19.2010
> Drive out the Hole In The Rock Road. Visit Devil’s Garden and Metate Arch.
> Drive to Dry Fork of Coyote Gulch. Hike down to Peek-a-boo and Spooky slot canyons. I hiked the loop up Peek-a-boo and down Spooky while my wife hiked with another lady hiker up Dry Fork and then down to the bottom of Spooky.

Tuesday 4.20.2010
> Hike Lower Calf Creek Falls (my third hike here and my wife’s second) and scramble up to two sets of pictograph panels.

Wednesday 4.21.2010
> Drive the Burr Trail road from Boulder to Notom (my fourth time on this scenic route and my wife’s second). Photograph in Long Canyon and along Waterpocket Fold. Race a rain storm north on the dirt (rapidly turning to mud) portion of this route.
> Hike to the Wild Horse twin caves across the slickrock

I'm experimenting with these LED-panels that are only 12 mm thick. They are waterproof and have a light efficiency of incredible 105 lumen/W @ 6500K.
Each panel is 300 x 600 mm and 36W.
In this way I can use the panel itself as a shelf and add as many I want in height.
They come in various sizes and should be ideal for flask growing as they emit very low heat.
