One of the notes I made in my 1st draft was to clarify if this was a landslide or a blockfield (or both?) My MC and her caravan are traveling through the mountains (mountains resemble the Rockies more so than Appalachia). They come across a stretch of rocks and boulders and have to climb down the slope that it had made. In my mind, I am picturing something that looks like this (but sloped): and this: (both from wikipedia: Blockfield) but both are "associated with alpine and subpolar climates." My MC is traveling 2-3 months after a terrible storm (their rainy season). The storm season is brief, but it causes a lot of damage and has caused a rockslide. When i googled rockslide i get these images: .....are these not blockfields too? Does a rockslide make a blockfield? Despite the google images, "rockslide" just makes me think of little fist sized inconveniences . It just doesn't paint the right picture in my mind....
I always go with "scree." What a lovely, lovely word. I would probably use rockslide to describe something sloped and relatively recent-looking. Blockfield seems to be flatter and more... permanent? Not sure. Long live scree!
Blockfields are very old and I believe they are not catastrophic, whereas rockslides are disasters. The images you give don't look like scree to me, which I have always understood to be small and fragmented, deposited over time at the base of a slope; whereas rockfalls produce larger debris, deposited all at once. I'm sure there is overlap, however.
