Gibson Jack Lower Trail - Caribou NF

Post by dbhguru » Sun Jul 10, 2011 4:52 pm

WNTS/ENTS,

This morning Monica and I went in search of a stand of old growth Doug Fir on Lower Gibson Jack Trail in the Caribou NF. We found the old growth plus more. The wild flowers along the way were superb and the views excellent. It was a delightful trek in an area that is highly excessible and popular, but only for people you don't mind meeting on the trail. The bikers and hikers are courteous. You don't see the throngs of people shuffling along, looking bored or indifferent as is frequently the case on popular short hikes in the big national parks. We did have to watch out for moose. There is a healthy population of those big animals along with elk, mule deer, black bear, mountain lion, coyote, and a few miscellaneous varmits.

I took about 50 photos including 8 or 9 of the Doug Firs, but the trees are really secondary on this trail.

The first three images were taken near the start of the trail looking back.

Now some wild flower shots.

And the OG Doug Fir - not too much to look at, but satisfying in ways I'll explain.

The Doug Firs are not large in diameter. The big ones are 8 to 11 feet around. So there wasn't much point in taking photos up close. Heights are a little more impressive.
I measured Doug Firs to heights of 110.0, 114.5. 127.0, 133.8, 108.0, 116.0, 112.0, 113.0, 109.0, 105.0, 127.2,
111.0, 113,5, and 138.6 feet.

There are plenty of firs between 90 and 110 feet, a fair number between 111 and 115, and a small number between 116 and 125 feet. I found 3 over 125, as listed above.

James,

Yes, the Gibson Jack area in the Bannock Range of southeastern Idaho is a candy to the eye. The elevations are not great (5,100 to 7,500 ft), so feeling the altitude is not a problem if coming from low elevations. Here is another view of the Doug Firs.

In the drier climate, the old firs commonly reach heights of 90 to 110 feet, with a small percentage between 110 and 120. A very small percentage reach to 121 to 130, and a very occasional tree tops 130. Add water and protection and the numbers above go up 10 to 15 feet.

What do you use to site and measure the heights of the trees?

Marc,

Those mountains are in the Pebble Creek area. There are 3 peaks in that small range over 9,000 feet. The range rises approximately a mike above its base. There are no foothills. The impact is considerable. The area is south of Pocatello - a long way from Borah Peak.
