I live in unincorporated Larimer northeast of Estes, along CR43. My personal is 41" on May 19th 2017. I have heard of a 53" storm in November 2013...before I moved here. I have lived in 2 snow belts in the great lakes region - Northwest Indiana and Chardon, OH. So, I have seen some much larger snows. One in particular while driving in NW Indiana on I-80 thru a 4" per hour snow squall. That is scary stuff.
In Estes there is a lack of historical climatology records, so not much to compare.
