This creepmeter is creepmeter is a reoccupation of the SJN1 creepmeter 
initially installed by Robert Nason in 1967 and described in Schulz (1989). 
That creepmeter was abandoned in 1985 following several problems at the site.  

In 2004, Roger Bilham (U. Colorade) installed an instrument which operated for about
10 years but abandoned due to frequent flooding.

In 2020, Bilham installed another creepmeter, which hopefully, is resistant to flooding.
In 2022, day of year 151,  the baseline of the instrument was lengthened.

The data provided here starts in 2004.  The files between the pre 2014 and
post 2020 intervals have been merged, but the offset between the two sets
needs to be estimated.
