Snowfall is an important element of ecological continuity in nature and durability in human activities. Climate change, whose effect we feel in almost all areas of life, also shows its presence in snow climatology. In Turkey, snowfall is mostly seen in the Eastern Anatolia Region and the highest snow cover depth is reached in Eastern Anatolia Region. The aim of the study is to test whether there is a trend in the monthly maximum snow cover depth in long times (1970–2020) in the Eastern Anatolia Region. Monthly maximum snow height data for long years (1970–2020) from the General Directorate of Meteorology (MGM) of the provincial central meteorology stations and Mann-Kendall Trend Analysis method were used. As a result, it is seen that there are statistically significant decreases in the 95% confidence interval in the majority of stations at monthly maximum snow cover depth. It is noteworthy that there are increases as well as decreases in the changes in the monthly maximum snow cover depth. It is an important finding that especially Kars station has an insignificant increase in the monthly maximum snow cover depth. Decreases in neighboring provinces may be a sign of clustering. In this context, the change can be examined by using mostly station data and spatial statistics methods.
