Yesterday morning a very strong storm roared across northern Illinois. It chased me to my office at Mayslake Forest Preserve, and I had barely got in the door when the view suddenly was obscured by a wall of horizontal rain. Winds reportedly reached 80mph. This storm was catastrophic for several trees on the preserve. One of the two venerable weeping willows in the low southeast corner of the mansion grounds lost a significant part of its top.
Elsewhere on the grounds, one of the white firs lost its top.
White fir has remarkable, resinous oval cones.
Free-growing wild trees were not exempt. One of the largest shagbark hickories in the north savanna also lost its top.
Changes in nature are not always gradual.
