What's the difference between scree and talus?

Scree consists of smaller rock fragments, usually pebble to fist-sized, while talus refers to larger boulders. In practical terms, scree tends to shift and flow more readily underfoot, whereas talus requires more careful placement on individual larger rocks.

Is it easier to go up or down a scree slope?

Going down is much easier. Descending scree can allow relatively quick progress with the right technique, while ascending is exhausting—you'll slide half a step back for every step up as the loose rocks shift beneath you.

Should I avoid scree slopes when it's wet?

Yes, absolutely. Rain-slicked rocks lose what little friction they had, and the whole slope becomes alarmingly mobile. If water is running down a scree slope, find another route.

Common Hazards

Scree Slopes Explained

Scree slopes are fields of loose rock that shift under your weight, turning descents into ankle-twisting slides and ascents into exhausting backward slippage. Knowing whether to tackle them straight down, traverse diagonally or avoid them entirely depends on scree size, slope angle and what lies below.
