By dividing Z with the equivalent return of a 1 mm drop in a volume of a meter cube (Z 0) and using the logarithm of the result (because the values vary greatly from drizzle to hail), one obtains the dimensionless quantity dBZ: â â¡
The trail measured 2,168.1 miles in 2001. The total distance of the trail changes slightly from year to year as trail maintenance groups reroute the trail as needed. An Appalachian Trail thru-hike takes between five and seven months to complete the entire trail. (About 20 percent of hikers who begin the trail will complete it.)

Appalachian Trail in NH. The AT is a 2100 mile foot trail running along the Appalachian Range from Springer Mountain in Georgia to Mt Katahdin in Maine.

From downtown Hanover the trail heads up Velvet Rocks to the Velvet Rocks shelter.
