10/03/06
Middlesboro, KY (36.63 N -83.70 W)
I have seen at least 60 Monarch Butterflies headed towards Tennessee.
This is the first time I have witnessed them migrating in our area in
such noticeable numbers.The number above was witnessed in about 30 minutes
time.

Kittery, ME (43.11 N, -70.73 W)
On 9/03/06 around midday, we were walking in Fort Foster Park in Kittery,
Maine and noticed so many Monarch Butterflies, we had to sit and count.
In a 5 minute interval, we counted over 80 individuals.
09/29/06
Scottsburg, IN (38.69 N, -85.88 W)
I finally saw a monarch migration! While traveling south on Hwy. 31 south
of Henryville, Indiana I started spotting monarchs one after another.
I pulled over to the side of the road and I counted around 50 within a
20 minute period. Indiana is not known as a great migration pathway so
this was an unexpected surprise.
09/27/06
Eureka Springs, AR (36.30 N, -93.54 W)
I saw 15 Monarch butterflies during our 30 minute recess from 2:15-2:45
P.M.

Summit, AR 36.2829 -92.6792 (36.28 N, -92.67 W)
Starting at 1:33 PM, 71 monarch butterflies were sighted in a 15 minute
time period.
09/28/06
Saint Paul, AR (35.85 N, -93.72 W)
My students and I counted 41 monarchs in 20 minutes, flying south, southwest
very high in the sky. The monarchs appeared to be in an air current because
they were moving quickly with little effort.
10/2/06
Assateague Island, Virginia (37.94 N, -75.31 W)
The biggest day yet: “Monarchs migrated down the island by about
1,300 per hour for most of today. It was quite a show!" reported
Denise Gibbs of the Chincoteague Monarch Monitoring Project. >>
