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.) The average cost of an Appalachian Trail thru-hike is approximately $3,000 (about $1.50 per mile), not including gear.
The master-mind behind this was Benton MacKaye, who proposed the idea in 1921. With the help of countless volunteers, it became a success in 1937, and it is still known today as one of the most popular trails in the world. Running through 14 different states at 2,179 miles long, the Appalachian Trail is the nation's longest marked trail! It goes through several National Forests, National Parks and State Parks. The lowest elevation along the trail is near the Trailside Museum and Zoo at Bear Mountain in New York at 124 feet. The highest elevation stands at 6,625 feet in Tennessee on Clingman's Dome.
