February 28, 2010 Cross country skiing in Lake Fairfax Park, Virginia. Again, about 2.5 miles and a faster-than-yesterday 0:45. With Ania.
40F (4.5C), mostly sunny and windy. The very extensive athletic fields had a pretty good layer of wet snow left. In fact there was more snow on the exposed fields than in the woods. The open areas must have had quite a bit more accumulation of the white stuff to begin with.
March 2, 2010 Nordic Walking on the streets of Vienna and Oakton. About 3 miles. 0:38:30.
Pretty good time, considering the need to go around very numerous 1-1.5-meter piles of snow left-over on sidewalks from shoveling, snow-blowing and plowing.

This is Ania at about 4,000 feet, next to the “Upper Slope Outhouse”, between Roundtop and Bald Knob. March 7, 2010 More cross country skiing at White Grass. This time, we climbed through the fairly easy, but long Three Mile Trail, above Roundtop, just below Bald Knob, to the altitude of about 4,000 feet. About 7 miles. Four hours.
The higher elevations have a markedly different type of snow and vegetation. Skied a tiny bit into the incredible Dolly Sods Wilderness area.
The weather and the snow are simply perfect!
March 8, 2010 Third day of country skiing at White Grass. After about an hour, I left Ania to enjoy the lower glades and trails and headed to explore some of the mid-mountain intermediate and expert trails, where I have never skied before.
About 6 miles and two hours. Some of the steeper, slicker and narrow trails had a definite “oops” factor to them, as my skis are not equipped with steel edges.
Another cloudless, gorgeous day – about 45F (7C).
It was hard to have to head home, as this could be the last hoorah for this winter season.

Light rain and 45F (7C). Serious rehabilitation work going on along Glade Stream. Machinery, wide, wooden “roadways”, etc. I seems to me like too many trees have been cut in the process…

March 21, 2010 Turkey Run Park, Virginia. A loop of the park, including a section of the Potomac Heritage Trail, which wasn’t easy to traverse in sections, because of the high water level in the Potomac River. About 3.5 miles. 1:05.
