Results show that in addition to such environmental characteristics as trail slope, trail difficulty, land use and elevation, age has a strong, non-linear influence on walking speed.
Regression modeling revealed that trail position, trail slope alignment angle, grade, water drainage, and type of use are significant determinants of soil loss.
A short walk away is the Ballena Trail, sloping upward into the mountainside and dotted with otherworldly melon cactuses, their caps of red flowers bursting out on top.
So bring your family or some good buddies and hit the trails, slope, or beaches.
Elongate parallel slicks may also form over and migrate with the trailing slopes of internal waves.
Key factors include trail grade, slope alignment angle, tread drainage features, and the amount of rock in tread substrates.
Without the help of switchback trails, the slope is so steep that one can't help but engage in an up-close-and-personal examination of its flora: pale green and orange lichens, cushiony clumps of moss, yellow snow buttercups and the aptly named sky pilots, their purple-blue flowers poking out improbably from the rock debris.
It has ice-skating and rock-climbing facilities, ski lifts, and trails and slopes to Squaw Peak (8,885 feet [2,708 metres]).
For the two scientists, "all this" had included hiking down trail-less slopes of loose rock and soil past sharp, charred stumps of manzanita and oak, hauling gauges and sensors, solar-powered communications equipment, a surveying device with a tripod, and assorted mounting poles, clamps, cables, drills and batteries, as well as cement and other supplies.
The dramatic increase in soil disturbance on the skid trail with a slope > 20% is presumably associated with the difficulties of skidding on steep terrain.
Then, choose a trail that changes slope and pitch several times.
