Two days before breakup:
Plots below assume AST throughout the record.
A large drop this year (earlier breakup) but is within the bounds of noise in this very noisy system. It does follow the downward trend from the 1970s.

The Annual Nenana Ice Classic is Over for Another Year
After an initial movement 2 days ago an ice-jam prevented full movement of the tripod and the clock was not stopped. However, the Tanana River officially broke up on April 24th at 2:25 P.M. Alaska Standard Time.

Tripod moved but not moving
Not free of ice but no more tripod:
So how does this extended date fit in with previous data.
2 plots
one timed from start of year
this one timed from vernal equinox
Seems to be following a declining period with a few early peaks
