@jurban Probabably a little of both. We've caught large dust clouds of avalanches "in the act" so it would not be impossible to interpret this as part of the lingering dust cloud.
Too hot outside and need something to do inside? Our August image catalog update awaits:
Ice Blocks Sliding Down Dunes
Russell Crater hosts a large dune field. In the spring, carbon dioxide ice on the gently sloping side of the dune sublimates (evaporates) first, leaving a warm sandy slope.
At the crest of the dune alcoves harbor ice longer, which then breaks off in large chunks and slides down, forming linear gullies. Sometimes the sliding ice block leaves a cloud of dust, as we see in this image.

HiRISE 3D: Crater Rim Deposits near Planned ExoMars Landing Site in Oxia Planum
This is part of our August image catalog update (dated 6 Aug). https://www.uahirise.org/anaglyph/
Spiders in Manhattan
After ice sublimates and erupts, thin debris falls to the surface of the ice in dark fan-shaped deposits, oriented by the wind blowing at the time of the eruption. The surface below the ice is eroded into channels known as araneiform terrain, colloquially called “spiders.”

HiRISE 3D: Abrupt Transition in North Polar Stratigraphy
Well, now that’s a steep cliff. Collapse of material at some point?

Dunes in Northern Summer
This image was taken during the Martian northern summer, so there is no frost present on the dunes. The dunes closest to the base of the polar cap are long and parallel, indicating strong winds from the direction of the cap. As they get farther away from the polar cap, they start to form more crescent shaped dunes, called barchan dunes.

HiRISE 3D: Flow Structures in a Noctis Region Trough
This observation shows probable impact melt and structures from nearby Oudemans Crater.

Inverted Terrain in Eridania
The Eridania Basin is thought to have once contained a large sea. This image shows the Gorgonum Basin, which lies along the eastern edge of Eridania.
The ridges and channels are interpreted to have formed by water flow, either along the surface (channels) or in the subsurface (ridges), providing clues to the water history of Eridania.
The Color Wonderland of Mawrth Vallis
Mawrth Vallis has some of the most spectacular color variations seen anywhere on Mars. This color variability is due to a range of hydrated minerals—water caused alteration of these ancient deposits—which is why this site is of interest to study the past habitability of Mars.

A Triple Crater
This image shows an elongated depression from three merged craters.
The raised rims and ejecta indicate that these are impact craters rather than collapse or volcanic landforms. The pattern made by the ejecta and the craters suggest this was a highly oblique (low angle to the surface) impact, probably coming from the west.

HiRISE 3D: Possible Exposure of Polar Layered Deposits
The goal of this observation is to determine topography in an area not observed by MOLA (Mars Orbiter Laser Altimeter).

To Great Depths
This image from eastern Hellas Planitia shows some of the unusual features on the basin floor. These relatively flat-lying “cells” appear to have concentric layers or bands, similar to a honeycomb. This “honeycomb” terrain exists elsewhere in Hellas, but the geologic process responsible for creating these features remains unresolved.

HiRISE 3D: A Cliff in Hellas Planitia with Linear Gullies
This area contains a significant scarp. Other observations along this scarp show highly visible gullies. CTX images show darker colored ground in this area.

An Inverted Channel in Aniak Crater
'The objective of this observation, also available in Context Camera data, is to examine a valley that turns into a ridge in the southeastern part of Aniak Crater. This is probably an example of an inverted channel, so the material that formed it was more resistant to erosion than the surrounding terrain.

HiRISE 3D: A Possible ExoMars Landing Site in Oxia Planum
This image again highlights HiRISE’s crucial role in selecting potential landing sites, not only due to high resolution, but for 3D images to help assess risk.

Small Channels near a Central Pit in Terra Cimmeria
There are small channels visible in Context Camera data that are of interest at HiRISE resolution. The host crater is (relatively) fresh and thus may be geologically young; the channels incised on both its northern interior rim and floor may be candidates for impact induced hydrothermal activity.

Well-Exposed Layers near the Rosalind Franklin Landing Site
The Rosalind Franklin rover from the European Space Agency is expected to arrive at Mars in a future year, to study ancient layered bedrock in the Oxia Palus region about 80 kilometers to the northeast of this image location.
This observation is part of a stereo pair of a 1.5 km-wide crater with excellent exposures of the bedrock layers, that will help reconstruct the stratigraphy in the region.
HiRISE 3D: A Crater with Steep Slopes
There might also be gullies here, in a region where gullies are not typically present due to elevation.
