In the years 2018 and 2019, I spent months walking East across India with Paul Salopek on the Out of Eden Walk (For details, see: https://www.nationalgeographic.org/projects/out-of-eden-walk/#section-0). His trail started in the Great Rift Valley of Ethiopia in East Africa, roughly following the path of the early human migration out of Africa and across the globe.
The India trail of the Out of Eden Walk started from the India-Pakistan border at Wagah, Punjab. It then moved East through the Indus Basin, followed by the basins of West flowing rivers like Luni, then a large chunk through the southern Gangetic plains in Central India before crossing over to the Brahmaputra basin close to Siliguri in West Bengal. The crossover to Myanmar happened at Moreh in Manipur, also incidentally very close to the basin boundary of Brahmaputra and Irrawady. He entered India in March 2018, and crossed over to Myanmar in July 2019.

I was taken aback, but it was not very unusual to see in the peak of monsoon. So as we usually do, I took a screenshot and put up on SANDRP FB page with a warning that this could lead to floods. I did not realize that this was the beginning of an unprecedented wave of floods for these regions that may extend to Ganga basin as I write this. Such purple patches generally disappear in 24 hours, since the rains do not last to long. However, in the case of current phase, not only the purple patch has last now for 42 hours, it has extended to the west, all along India Nepal region along the southern boundary of Nepal.
