The deep freeze in December 2016 saw consistent temperatures between -20C and -30C (-4F and -22F) that caused the ice jam on the Nechako River in Prince George. The town declared a Level 1 emergency when the ice jam reached the confluence of the Fraser River. Ice jams cause the river level to rise and can lead to flooding and damage to the structural integrity of bridges . The ice in an ice jam is dangerous and unstable and not suitable for walking on.
A female Rufous Hummingbird (Selasphorus rufus) in flight. They are difficult critters to get a shot of and to freeze the motion this was taken with a shutter speed of 1/2500, that’s less than half a millisecond. Hard to believe these tiny birds travel over 3,200 km (2,000 miles) from Alaska to southern Mexico and back, having to cross mountain ranges as high as 3,800 m (12,600 ft). Measuring only 7cm (2.8–3.5 in) long, it is the longest bird migration on earth when measured in body lengths. They weigh a miniscule 2 to 5 g (0.071 and 0.176 oz). Kinbasket Lake, British Columbia, Canada.
