Dear Reto Sterchi and co-authors

Thank you for the submission of your very interesting manuscript “Exploring the relationship between avalanche hazard and large-scale terrain choices at a helicopter skiing operation – Insight from run list ratings”.

As you know, three reviewers have now provided detailed reviews, which you have replied in thoughtful detail to. The reviewers recommended minor and major revisions, and therefore I would like to invite you to submit a revised version of your manuscript.

Would you please also provide an ‘author’s reply’ to the reviewers (feel free to use the same words that you used in what you have already uploaded). Please can you also include a track changes document between the old manuscript and the new one (you can include this as part of your ‘author’s reply’). Further information for the guidelines you will find at https://www.natural-hazards-and-earth-system-sciences.net/for_authors/manuscript_preparation.html - author’s response.

In addition to the suggestions from the reviewers, I would like to suggest the following technical items, in most cases ‘minor’:

(a) Please check all figures and adapt them to the guidelines of NHESS
(b) Page 6: please adapt the equation according to the guidelines of NHESS
(c) The quality and readability of Figure 5 is low and the font size is too small, please adapt
(d) Please consider that the figure caption should be written that the figure is understandable without further reference, please adapt the caption of Fig. 6

I look forward to seeing the next version of your manuscript which I will not send out for further review, but rather, will make the decision myself, assuming no major items come up in the revised manuscript for which I need outside reviewers to aid me in my decision.
