On 16 and 17 June 2013 a cloudburst combined with the collapse of a moraine-dammed glacial lake above Kedarnath sent water, mud and rock down the Mandakini valley.
What happened
The flood arrived in the pilgrimage season, when the valley was full. The town below the temple was largely destroyed. The death toll across Uttarakhand ran into the thousands and has never been established precisely, in part because a very large proportion of those present were pilgrims from elsewhere who were not on any local register.
The stone
The temple itself survived, and the reason is a single boulder. A large rock carried by the flow lodged against the temple's upstream wall and split the debris flow around it. The structure took damage but stood, while much of what surrounded it was scoured away.
The boulder is now venerated. It is called Bhim Shila, and it sits where it stopped.
It would be easy to write that sentence as though it settled something. It does not, a rock deflected a debris flow, which is a thing rocks do. What it does illustrate is how quickly a site absorbs an event into its own frame of meaning: within a season the stone had a name and offerings on it.
Rebuilding on the assumption of recurrence
The temple reopened after roughly a year of clearing. The approach has since been re-engineered: protective walls, a realigned path, controlled numbers, mandatory registration, and a helicopter service.
The design assumption is explicit: it will happen again. The Himalaya are young and rising, the monsoon is intensifying, and glacial lakes above the pilgrimage routes are growing. The rebuilding is not a restoration of what was there in 2012 but a different structure of risk management around the same shrine.
The priest from the south
One older detail survives all of this untouched. The head priest at Kedarnath is traditionally drawn from the Veerashaiva community of Karnataka, a South Indian lineage serving a Himalayan shrine, while a few days' walk away at Badrinath the head priest is by tradition a Nambudiri Brahmin from Kerala.
Two of the highest shrines in the western Himalaya are served by priestly lineages from opposite ends of the subcontinent. It is the clearest surviving trace of the all-India network of shrines that the tradition attributes to Adi Shankara.
