there are many different entries in the attribute table, please add column name for measured snow height

One accompanying file reffered to this point-layer as snow depths, but I checked the attribute table and in my opinion it only contains GPS-related fields. How should we deal with this layer, leave it in and refer to it as position points in the area of interest, or should we take it out, as it had no direct value to anything.

was there any information provided on how these classes are defined?

Yes, Feistl et al. (2014) defines theses forest as "dense" with a canopy density greater than 50% and as "open" with a canopy density below 50%. The canopy density was derived from orthophotos of each site.
Suggestion for the README: "Based on Feistl et al. (2014), forest classes are defined by canopy density: stands with >50% canopy cover are classified as "dense", those with <50% as "open", based on 25cm-resolution orthophotos

what is meant with source and final?

The original/source CRS of the layers was the old Swiss CRS (EPSG:21781), however since SwissTopo uses for its DEM the new Swiss CRS (EPSG:2056), I had to change the CRS for all layers provided by the SLF to prevent location conflicts between DEM and event layers.
Should I explain this better in the README or leave this information out completely? Suggestion: "All event layers were originally in LV03 (EPSG:21781). Since SwissTopo DEMs are in LV95 (EPSG:2056), all layers were reprojected to EPSG:2056 to avoid misalignment."

if no thickness provided, how is this defined?

In Feistl et al. (2014), the reported release volumes are derived from mapped release areas combined with an assumend/estimated fracture depth, which are not specifically stated in the paper.
