Sometimes the mist rises from below, even in the late summer or early autumn. I suppose the patch of haze in the upper lefthand corner of this picture is nothing but the light of the nearby lantern. I should have used a hood around my lens, but I didn't happen to bring one with me.
Tomorrow, rain is expected. Today the ground was soggy, and there were more clouds than clear areas of sky, but there has been no rain so far. I noticed an odd cloud formation over the lake, along the east side.
