It was a pretty mild winter this year without any particularly severe cold snaps and without any thaws either. After a green Christmas we had a good blanket of snow shielding the ground all through January and February. Now soneone has flipped the switch and spring is running at full speed.
Below are three photos of the north side of the berm from March 20 to March 30. Ten days ago it was still winter on the north side of the berm. Now the snow has practically disappeared and the crocuses are out.
