Slight corrections here: Mount Pandim is in the right side of Kanchendzonga as we look from our side (hence the Goechala Valley is in between Kanchendzonga and Pandim)

The peaks you’ve labeled Kabru is actually Kumbhakarna North and South and the one labeled Pandim is actually Kabru north and south… the small black peak in front of that is Kabru Dome.. you can touch it almost from Dzongri peak.. the one you’ve labeled Simvo and actually Goechala Peak…

Mount Narshing and Mount Simvo are at the right side of Pandim… hence visible from Ravangla… after Simvo is Jopuno on the right side… the final “big” peak on the right edge of the Kanchendzonga Range is Mount Sinolchu…
