March 16 [Day 12] (Terry Waters) When Terry arrived at 0730 there was steady snow and all ridges were obscured. At 1200 the ridges showed signs of clearing so observation began. The temperature at 1200 was 1C and rose to a high of 3C at 1400 and was still 2C at 1800. Ground winds were SW-W all day generally 10-20 gusting 30 km/h, and ridge winds were strong SW-WSW gusting to nearly 100 km/h to 1500 after which they moderated 30-40 gusting 60 km/h. Cloud cover was 100% stratocumulus all afternoon which was thin enough to allow very hazy sunshine. The eastern ridges were more-or-less clear all afternoon, but the west was 50% obscured and the mountains to the south were often invisible. The first raptor was the season's first migrant Northern Goshawk (an adult) at 1310 followed by adult Golden Eagles at 1315 and 1355. An adult Cooper's Hawk at 1442 was also a season's first and the 5th and last bird of the day was another adult Golden Eagle at 1545. 6 hours (126.58) COHA 1 (1), NOGO 1 (1) GOEA 3 (252) TOTAL 5 (279)


Eagle #78453 started the day by flying due east into the foothills, probably to avoid the same downslope snow conditions that were experienced at Lorette. It then resumed its flight to the NW but by the end of the day it was still well south of the North Saskatchewan River.
