Stalactites
I don't have to go down in a cave to see stalactites.
I am sitting in the house watching icicles drip. A drop of water swells on the tip -
then SPLAT! it drops on the snow below.
Just like water dripping through the rock of a cave and running down a stalactite.
The icicles are not getting shorter.
They are getting longer and fatter.
Just like a stalactite grows a little with every drip.
When the drips hit something on the way down, new icicles are forming.
At the bottom bits of ice are growing up like stalagmites.
(The 'mites go up and the 'tites go down)
In a rock cave it takes ages and ages for a stalactite or a stalgmite to grow.
The ice ones grow very quickly...drip...drip...drip.

Groundhog's Day
Which is good fortune on the day
When we see how long winter will last
By the shadows groundhogs cast.
Seeing none, we anticipate:
we won't have very long to wait:
soon birds will sing their springtime song
and sun will make the green days long.

A hole in the ice
It's really a heater. Even when the ice is thick (it is about 3 inches in this picture) the heater will keep a hole open.
The hole will let the pond breathe.
You didn't know the pond needed to breathe?
Yes, the decaying plants on the bottom of the pond give out gases that need to be exchanged with oxygen from the air so that the water is sweet and good for living things.
Is anything living in the pond in the winter?
Yes. Under all that ice and snow our tadpoles and frogs and turtles and snakes and dragonfly babies are sleeping, waiting for Spring.
Yes. Under all that ice and snow our tadpoles and frogs and turtles and snakes and dragonfly babies are sleeping, waiting for Spring.
So we have to take care of the water under the ice all winter.
