I took this photo from our kitchen window looking over to our neighbors house.

Petrified Forest National Park

After leaving the Grand Canyon, I drove east on Interstate 10 to visit the Petrified Forest National Park. In order to appreciate this place, you must exit the Interstate, get out of your vehicle, and take the short walks that are available. From Interstate 10 on the north side of the park there is a road that will take you a short ways into the Painted Desert, then it turns south to take you through the Petrified Forest. It comes out on U.S. 180 east of Holbrook, where you can easily pick up the Interstate again. It may take you a couple of hours to drive through the park, but it is well worth the slight detour.

The colors in some of the pieces are incredible. It looks like someone came along with a chain saw, a very large one in some cases, and cut up the “trees” into small pieces.... then they went and tossed those pieces and scattered them around the desert floor. Of course, the Rangers deny any such thing.

Actually, the Petrified Forest, as we see it now, is but a shadow of its former self. Before it became protected as a National Park, people came and took away quite a bit of the petrified wood. Even now, with a warning of a fine of several hundred dollars, people still walk off with bits and pieces. I can understand the attraction. It is beautiful stuff and the colors are startling, but I resisted the temptation and went away empty handed, except for the photographs I took.

Glacier

Here is more of an close up of the mountains. You can see the snow and a glacier almost right in the middle. It is the closest I could get to the glacier at this time. According to a sign at the viewing center there are more than 60 active glaciers on the mountains that are in Olympic National Park.

Passing the Link-Love Around

There's a love virus meme being propagated through the genea-blogosphere and kinexxions has been tagged twice! Thanks go to both Thomas MacEntee at Destination: Austin Family and Sheri Fenley at The Educated Genealogist.

The rules associated with this particular tagging thingy are that the tagged blogger

Researching Mount Rainier's Glaciers

Everyday, climbers inquire about thinly covered crevasses, glacier conditions, or that “bergschrund” on top of the Emmons. And we’re here to share what we know about the Emmons, Kautz, Tahoma and other major glaciers on Mount Rainier. But we also wanted to let you know that the NPS is actively monitoring these glaciers in an effort to better understand how the climate is affecting them and how these glaciers are affecting the mountain and the surrounding areas. This is important stuff when you consider that Mount Rainier’s glaciers are a primary water source for many Washingtonians, while at the same time a potential geological threat to communities in the floodplains downstream.

Basic Science Recap: Glaciers are permanent sheets of flowing ice that erode mountain slopes, carve valleys, and affect the geography of the park. Rainier’s glaciers have an “accumulation zone” (where more snow gathers than melts) and an “ablation zone” (where more snow melts than accumulates). The most recent detailed measurements (1913 to 1994) on Mount Rainier indicate that the combined glacial area has receded by a 1/5th, and that the total volume of glacier mass has decreased by 25%.

The Nisqually and Emmons are part of a long-term monitoring program making them the most scientifically prodded glaciers in the park. The current study is a cooperative venture between Mount Rainier and North Cascades National Parks and includes field measurements of snow depth, snow density, and snow/ice melt. It includes an annual series of terrestrial, aerial and satellite images. To better understand what's going on, researchers place “ablation sticks” (PVC poles) at various elevations and locations on the Emmons, Ingraham and Nisqually Glaciers. In the spring, researchers us a steam drill to sink these stakes into the winter snowpack until they reach the glacier ice. Then throughout the season, researchers measure the snow accumulation and more importantly, the rate of snow melt. This allows them to calculate the net balance of the overall snow and icepack. The graph below shows the results gathered since 2003. As you can see, the overall mass balance of the ice is decreasing.

So why are we sharing this geeky science information? Well, we like it, but also because climbers have been noting the PVC poles buried on the glacier and have asked, “What’s the plastic pipe all about?” Those PVC poles are the measuring sticks. If you keep your eyes peeled on your next summit attempt, you may note one or two of them on the Muir Snowfield, Nisqually, Emmons, or Ingraham Glaciers. If you do see them, please do not disturb or remove them.

For more information on the glacier monitoring being conducted by North Cascades National Park, check their website. And if you’re interested in the historical Mount Rainier glacier studies referenced above, check out the “Glacier and Glacier Changes” homepage on the Mount Rainier website.

Great day in the woods

After shooting this morning's sunrise on Lake Superior I spent most of the remainder of the day exploring a remote section of Hollow Rock Creek. Hollow Rock Creek has a couple of really cool waterfall areas that are difficult to get to... no trails lead to these areas, so you have to bush-whack your way in and believe me, the going is pretty rough!



Once you get to the waterfall areas, however, the effort is well worth it. The beauty of Hollow Rock Creek is not an "in your face" kind of beauty... its beauty on a smaller scale. You have to look closely to see it, but once you start to look you soon find yourself seeing things you would have otherwise missed. The weather was perfect for this day of exploration along Hollow Rock Creek: overcast skies with very thick cloud cover. The cloud cover makes for a very even, muted sort of light that is conducive to shooting under the forest canopy. Bright sunny days are less desirable when shooting in the deep woods as the rays of sunlight create areas of extreme contrast that are almost impossible to expose correctly in a photographic image.

Also, once most of the leaves have fallen off the trees, that doesn't mean that you should put your camera away and stop venturing out into the woods. It simply means that you should try looking other places to find your images... namely, along the ground! Its one of life's great pleasures to wander along a little creek like Hollow Rock and look for all these neat little things that catch your eye.
