Rarely has the month of May be more keenly anticipated than this year.
The cold temperatures and heavy snowfalls this April, while long needed
by the water table, left most locals keen for the lengthening days and
(hopefully) warmer temperatures that May promises. Also welcome will be
the first signs of green as leaves begin to emerge and the first flowers
add a sprinkle of colour to the meadows and forest floors. Higher up,
ground squirrels and marmots will re-emerge from a long winter sleep.
Few
things signify the arrival of spring more than the appearance of the
first wildflowers. The
prairie crocus
seems able to push its fuzzy purple flowers right through late spring
snowfalls. I've spotted them as early as April 23 in Bow Valley
Provincial Park. Look for them on sun-baked hillsides where they can
soak up the spring rays. Another spring flower, the
arrow-leaved
coltsfoot emerges with clusters of white flowers around the same
time. Because the coltsfoot is less showy, it's not as well known. The
calypso orchid
(fairy slipper), a delicate spring orchid, brightens the needle covered
floor of the lodgepole pine forest towards the end of May.

The
heavy snow this winter blanketed the Rockies with a welcome source of
spring runoff. Beneath the snow,
hoary marmots
and
golden-mantled ground squirrels were in a deep state of hibernation.
This month, we'll begin to hear the familiar calls of these high country
hibernators. Mixed with the whistle of the marmot and the high pitched
call of the ground squirrel is another familiar sound, the "peeeek" of
the pika.
While ground squirrels and marmots were sleeping away the winter, pikas
remained active, feeding on hay piles collected during the previous
summer. They create an intricate series of snow tunnels that they use to
navigate through their snowbound home.

Was that a snake?
We don't often see snakes
in the Rockies, but this apparent absence is just that, apparent. If you
know where to look, you may get the opportunity to see the occasional
garter snake. The Marsh Loop boardwalk at the Cave & Basin Centennial
Centre is the premier location for snake watching in the mountains. In
the spring, the snakes emerge from a communal winter den (hibernaculum)
to soak up the first rays of spring sunshine. This is the only known
hibernaculum in Banff National Park. Other spots for snake watching
include the Fenland Trail in Banff, and occasionally the Valley of Five
Lakes in Jasper.
The
recent movie Tomb Raider was based on a supposed alignment of all the
planets of the solar system. According to the movie, such alignments
occur every 5,000 years. In reality, there has never been such an
alignment. That being said, the next best thing is happening right now -
an alignment of five of the planets. Beginning April 26, and lasting for
about 10 days, the planets Mercury, Venus, Mars, Saturn and Jupiter are
forming an almost straight line in the western sky. Unlike the movie,
they are not lining up one behind another, but rather in a diagonal line
beginning with Mercury low to the horizon (only visible from an area
with a clear horizon) and climbing to Jupiter which will be easily
visible even in the mountains. A trip to the plains will give the best
view. Look west at sunset (around 8:30 p.m.) and focus your attention on
the two brightest of the planets, Jupiter and Venus. The line between
these two planets will contain Saturn and Mars. Mercury is even closer
to the horizon than Venus. click
