I have a mystery to solve. When I came downstairs this morning, I saw this in the snow. What do you think it is?

Good morning, another cold morning.  -7 at 8:00 AM but it is going to warm up.  One more night of below zero temperatures, then the warming up to 15 degrees on Friday, Sat 28 degrees, and then on Sunday 35 degrees leading into next week in the 40’s.  We will so appreciate those temperatures.  Stay warm, Stay safe.

Australia family and friends on Friday they will have 77F(25C) , Saturday will be 91F(32C) and warm for them on Sunday.  Stay cool, stay safe

Powell, Wyoming is having a warmup now.  Today at 28F, and then the weekend is in the mid 30’s.  Stay warm, stay safe

I have a mystery for you to help me with.  What caused this in the snow overnight?  I have an idea and will share it tomorrow.  I taught Elementary Science in Greene in 1976-1978.  One of my favorite units of study was tracks.  Seeing this made me remind me of that teaching.  Help me out and post what you think it is.  Thanks, till next time this is Becky Litterer, Becky’s Greenhouse, Dougherty, Iowa [email protected]  641-794-3337  cell  641-903-9365   Facebook Becky Kerndt Litterer, Becky’s Greenhouse
