6/1/2018 7:00 AM 1.09 0.0 0.00 0.0 0.00 We read the rain gauge at 7AM but we were busy with cleanup & getting critters back in the "right" pasture so I didn't get on until now to report yesterday afternoon/evening's major ppt event. We had what looks like massive amounts of rain plus dime to quarter sized hail. We still have drifts of hail. We were at the cattle auction in Billings yesterday so we only got in on the aftermath of the main storm here at the ranch. The Musselshell River Valley is a flooded mess. The only worse flooding I've seen here was in 2011. It's bigger than the 1967 flood which was "the big one" until 2011 in my local visual history. I have lived here since 1958 & my grandparents bought the ranch & moved here in 1942.
