they had to pick their way up precarious scree
Last autumn found me on a grueling research trip in the eastern Sierra, hauling heavy video equipment cross-country over loose scree and high passes.
The view back down the valley was also becoming grander as we rose high above the dark scree slopes and meandering river.
They nest in colonies in scree slopes along ice-free Antarctic and sub-Antarctic coasts, where they lay a single egg in a natural cavity.
Within an hour the gentle slope has careened skyward, and with each step loose bits of scree tumble down on those unfortunate enough to be bringing up the rear.
Melting ice gave way to continual rocks falling down scree slopes and into glacial streams and underground ice caves.
Leaving Alex to study for his biology degree, we walked out into the swirling mists and up the steep slopes of volcanic scree towards the snowline.
My knees were knocking just a little by the time I got down and I would recommend anyone who didn't like loose rock and scree to go back down the way they came.
The road turns to stone, the slopes to scree , and then came the top, the heather and our sandwich stop.
The roof gives one the sensation of sitting in a dry riverbed or mountain scree slope, particularly because it lacks containing barriers.
