Soil profiles are rarely preserved in the Himalaya due to active tectonics and erosion. We have studied two rarely well-preserved soil profiles developed on metavolcanic rocks namely Alaknanda soil profile (ASP) and Bhilangna soil profile (BSP) in Alaknanda and Bhilangna watersheds of the Garhwal Himalaya. Geochemical studies were carried out to understand the elemental mobility with reference to the least altered rock (LAR) in both the profiles and are compared. Differences in major element behaviour noticed are depletion of Ca and K in ASP, and depletion of Ca and Na in BSP. Trace elements also show variable mobility such as leaching of Rb, U and enrichment of Sr, Ni in ASP. In BSP, behaviour of these elements is just the opposite. Accumulation of ΣREEs in saprolitic layer and depletion in regolith of ASP suggest that rare earth element (REE) mobility took place during advanced stages of weathering. In BSP, increase in REE content from LAR to regolith suggests dominance of chemical weathering over physical weathering. This is also reflected in chemical index of alteration values which suggest variation of climatic parameters such as rainfall in the region.Keywords

Mountain roads are important lifelines and the most critical means for connectivity in the Himalayan villages of India. However, the inherent geological, geomorphological, ecological and climate fragility of the terrain warrants critical scientific investigations for the roads to sustain the vagaries of nature. Further, the increased frequency of extreme events with the ongoing climate change increases the potential impact of disasters. This note highlights the major challenges and issues faced with the ongoing road-widening projects in the country. It cautions against the uniform standard of road widening and the need to increase sensitivity towards appreciating the terrain fragility.References

This study analyses the causes and consequences of slope instability around the historical Himalayan town of Joshimath, Uttarakhand, India. The town is in the Higher Himalaya near the Main Central Thrust. The lithology constitutes fissile, shattered and sheared gneiss. Consequently, the slopes are prone to land subsidence and mass wasting. In the last few decades rise in population has led to a surge of infrastructure development, thus causing immense pressure on the finite resources and limited accommodation space on precariously balanced vulnerable slopes. Particularly, the unplanned infrastructure development, lack of adequate drainage and excavation of roads through unstable debris slopes are some of the reasons that seem to have accelerated the ongoing slope instability and land subsidence.Keywords
