After a cold night (the coldest April night in Scotland since 2013 according to the met office) it was a lovely sunny day. The clear conditions allowed for great views and an opportunity to take pictures of some locations I visit regularly to try to give an indicator of snow depth. In answer to my title question how deep is the snow on Aoanch Mor, well the answers depends (often I find when answering questions about snow and avalanches, I begin with “It depends…” or “It is complicated…..”). In absolute terms, in some locations the snow is deep; 5 metres easily, 10 metres in some locations. Just compare some of the features in some of today’s images with their summer counterparts below. On the other hand in relative terms, as compared to last winter for example, there is not a great deal, just compare today’s pictures with those taken at the end of last winter.
Last year to be fair was a fairly snowy winter. This year a combination of less snowfall and more variable winds has deposited less snow in Coire an Lochan and the other high North and East aspects. However, this season is not the worst, I have seen seasons when there is significantly less snow at this time of year. My feeling is that the amount of snow is slightly, but not massively, below average for the time of year.
Occasionally snow lies all year in Coire an Lochan. However, unless the weather does something quite impressive other next few months I suspect that this year won’t be one of them.

Great post, Blair. Who’s that odd chap in Easy Gully during summer??

Who knows! Perhaps he is making an audacious solo summer ascent of Easy Gully, or perhaps he is just lost! Glad you liked the post!

Hi Blair,
Regarding your photo of the 2 snow patches on the south side of Corrie an Lochan, as above.
Is it fair to say that this would be the “birth place” for a future glacier, should the planet cool as per the LIA period ending 1850 approx?

Hi Paul, that is a good question. In general terms yes glaciation would start in the high NE facing Coires. The amount of snow surviving through the summer during the LIA would certainly have been more significant, and there has been some debate as to whether there was a very small glacier in Garbh Choire Mor on Braeriach during that time. From what I understand the general feeling is that it was not quite cold enough for even minor glaciation in Scotland at that time.
