We hiked for 10 kilometers through the large valley Le Gran Plan, along the main pathway through the Dolomites, Alta Via Dolomiti. Altitude about 2,000 meters. The whole hike was a lesson on the massive amounts of moraine that glaciers can leave, and the progression from bare rock to small plants, shrubs and eventually trees.
The amounts of rock in moraines (photos at top) and talus (slope debris shown in photo above) are amazing. The boulders coming off the cliff are as big as houses.
