Analysing terrain data

The exposure grade describes the potential consequences of falling or slipping off the path.
Low Exposure: The path is on completely flat land and potential injury is limited to falling over.
Medium Exposure: The trail contains some obstacles such as outcroppings and rock which could cause injury.
High Exposure: Some trail sections have exposed ledges or steep ascents/descents where falling could cause serious injury.
Extreme Exposure: Some trail sections are extremely exposed where falling will almost certainly result in serious injury or death.
As the ski runs melt away at Squaw Valley, the flowers burst to life, and the season is prime for hiking.
Patches of snow at the highest elevations melt slowly all through the summer, feeding countless little streams and creeks that cascade over solid granite.
One of these is Squaw Creek, which drains down the backside of the mountain into the beautiful little Shirley Lake near the base of Solitude Chair.
To see the creek’s waterfalls and Shirley Lake, hike the Shirley Canyon Trail. This trail connects Olympic Village at the base with High Camp--the shops, dining, and swimming pool at the top.
You can easily skip all the touristy distractions at either end, though, and simply enjoy nature along the trail.
The Aerial Tram connects the endpoints as well, so you can ride the tram to hike the trail in only one direction, up or down.
If you hike the trail up, the tram ride down is free! Hiking up is not a gimme, however.
The trail is steep and hard to follow in some places, especially with snow on the ground.
Nonetheless, it is a popular trail and no problem for those accustomed to hiking on variable terrain.
The trail begins in the shade of tall trees along a babbling brook.
As the gradient increases, so does the drama of the scenery.
The creek tumbles in multiple waterfalls, wildflowers pop in varieties that shift with the elevation, and views open up of valleys below and peaks above.
One especially steep section requires traction on bare rock and possibly using your hands for stability. Eventually, the gradient lessens, and Shirley Lake appears ahead.
Enjoy a cool dip in the water, a picnic on its shore, or simply a quick pause to take it all in.
Next comes another steep ascent through bouldery mountain meadows to reach High Camp and the top of the Aerial Tram.
