Angel Rocks

At the Visitor Center yesterday we got recommendations for trails within easy driving distance from Fairbanks. Angle Rocks Trail, in the Chena River State Recreation Area, 50 miles away, seemed like the ideal hike. When we arrived and read the information board we learned where these Angels came from. Millions of years ago, hot magma rose beneath this region and slowly cooled. It formed the Chena Hot Springs pluton. (Remember Stone Mountain in Georgia two years ago? No?!! That was a pluton.) This huge mass of granite, estimated to be fifteen miles long, five miles wide and several miles thick, still lies below, but wind and water erosion have exposed small tips of it. These exposures are the Angel Rocks.

We realized that this area could be a geo-site which caused us to remember that we need to visit geo-sites in Alaska - we had forgotten all about that, although I don't know why with Mr. Spock frequently reminding us. We rushed back to check Dickas' book, 101 American Geo-Sites you've gotta see, and, to our wonder, there is only one geo-site in Alaska. We will be traveling to the location in the days to come, so stayed tuned.

The start of the trail parallels the North Fork of Chena River through mixed spruce and birch, 

Overlook Rock, the first tor - which is what these rock outcroppings are called. 

The tors formed millions of years ago when molten rock pushed upward and cooled before it reached the earth's surface. 

The surrounding earth slowly eroded, exposing the less erodible rock pinnacles. 

The trail climbs 900 feet to a treeless alpine ridge with fine views of the surrounding mountains.

to the west.

There has been a lot of rain lately (no kidding!!) and when we stopped at a picnic area on the way back we found it under water. We weren't a bit surprised!


Today's hike:
Length - 4.16 miles
Duration - 2 hours, 57 minutes (including lunch)
Elevation gain - 990 feet (101 floors on the Fitbit)
