Same thing happens occasionally here on Briar. Nothing like that this =
year but notice my car is covered at present even in the gagage.  All we =
have here are Spruce & Fir trees. =20

  In my experience I have commonly seen this phenomenon during the first =
half of June and I would suggest that the source is the staminate cones =
of pine, especially from Eastern White Pine.


  Since the1980's, until about 2004, I would spend a week or part of a =
week sometime during the first half  of June at Sherbrooke Lake =
associated with school groups experiencing nature and the out-of-doors =
in the camp setting.  Some years, particularly in June, we would =
experience deposits of pollen dust all along the  the lake shore at the =
camp end of the lake (the camp was at the northwest end of the lake.   =
There was one cove where we would find darkening, yellow-brown cakes or =
mats of pollen dust, stranded by dropping water levels. It could have an =
unpleasant odor from decomposing in the warm sun. =20


  I had concluded that the source was mostly from Eastern White Pine. =
During the first half of June the clusters of staminate (male) cones on =
White Pine are loaded with large amounts of the pollen dust, ready for =
the wind and water to carry it off.   White Pine appears to be a very =
common tree associated with lake country in the interior of  =
southwestern Nova Scotia, certainly this was true all around Sherbrooke =
Lake.


  My suggestion,
    Sherman

    Hi everyone:


    We had over two hours of continuous thunderstorm roll north of us on =
Saturday. (That would have been the ones RIchard reported driving =
through. We only got a few bursts of heavy rain...).  A bit late the =
same thing happened south of is in the Vaughan area.


    I went atalssing there this morning and all of the lakes had long  =
broad "spills" of bright yellow pollen. Some of these were several =
metres wide and aver 200 metres long. They looked as though someone had =
gone by in a boat and was dumping out yellow paint as they went. Falls =
Lake, and Mockingee Lake were affected. Someone I know was at a lake =
just west of there (North Canoe Lake) and it had the same thing. She =
also had photos of some of the hail that had fallen there on Saturday. =
The hail ranged from the size of dimes to the size of nickels.


    I'm guessing that it must have been blown into the lake, as the rain =
should have just brought it to the ground where I would have thought it =
would just stay put. Has anyone seen this before, or know what tree =
would make that much pollen?
