Why wouldn’t there be avalanches on Mars? It’s a rocky planet, and gravity doesn’t function any differently there. Same goes for Earth’s Moon. Satellites orbiting Mars have managed to catch them in progress, and that I believe was even before the InSight lander proved there are fairly strong groundquakes, which would trigger even more. And this is a planet known for its deep canyons…
Avalanche spire? There are avalanche on Mars? O.o
