|McBride Cabin > 2022-23-Snow
2023 was the 2nd highest snow fall at UC Berkeley's Central Sierra Snow Lab (CSSL) at Donner Summit since they started measuring in 1946. 1952 was the highest.
See Snow for more.
The snow in the yard reached a maximum of 9.5' at the beginning of March.
Warm weather and rain lowered the snow depth despite more snow in March.
The screen door with plexiglas in the bottom section held up well.
The snow went up 6" on the south living room screen
Snow on the back bedroom reached a dangerous level
Snow after Don Macey and I shoveled soft snow off the top so it would not absorb rain in the forecast. We got down to icy/hardback which would shed the water.
Dennis sent some guys over a week later after more snow accumulated.
It was too hard to shovel so they sawed it into cubes and shoveled/rolled them down.
4 guys 4 hrs. Each @ $64/hr. $992.
Snow shoveling adds at Tahoma Market. Rates have been $100/hr+

I rigged up a snow roof rake to get some more off.
Tom shut the sutters on the south side in the middle of April because there was still a lot of snow to come off that center section roof.

|Damp fresh snow
|Very wet snow
There were a lot more homes damaged. Here's a Tahoma home.
I compared the estimated load on the back bedroom with the building codes.
The building codes for our location require support for a load of 24.5 Pounds per square foot (PCF)
The estimated load of the 9 feet of 2 icy snow base layers with a frest layer on the top with rain forecast which would be absorbed by the fresh layer was 25.9 PCF. We had the additional problem with more snow on the north than the south which put us in greater potential risk, so we were in real danger of collapse.
People to shovel snow were all booked up.
Don Macey helped me get the fresh layer off the top, leaving the icy layer which would shed the rain, so we avoided a collapse.
See Snow Load (wight density) for the snow weight and how close we came to having a cave-in.
