An exploratory pollen and carbon isotopic study carried out from a 1 m deep sediment profile at the Paradise Lake (4176 m amsl) near Sela Pass has revealed vegetation vis-{\`{a}}-vis climatic changes during Late Holocene. Around 1800 yrs BP (around AD 240), conifer-broadleaved forest used to grow in the vicinity of the study site under warm and moist climate, similar to the prevailing present-day conditions which turned out to be comparatively more warmer 1100 yrs BP (around AD 985) corresponding to the Medieval Warm Period. The glaciers seem to have receded and tree line might have been closer to the site. Around 550 yrs BP (around AD 1400) decrease in Tsuga, Juniperus and Quercus suggests a trend towards comparatively cooler and less moist climate corresponding to the Little Ice Age. This is followed by an amelioration of climate more or less equivalent to the present day. Carbon isotopic analyses in sediments at different intervals reveal fluctuation of C-3 taxa dominantly throughout under variable moist climatic regime.
