We finally got a chance to check out the Reston portion of the W&OD Trail today. While much of the trail is clear, there is ice at the usual spots. These photos were taken late this morning (Monday, Dec. 28). They were all taken facing east.
The first photo shows ice at the Sallie Mae bridge across from Plaza America. It's not rideable without studded tires.
The second image image shows the hill on the approach to Buckthorn Lane (looking east). Both sides of the hill are ice covered.
The final image is looking toward Hunter Mill Road. This section will likely be the last to melt. There's a tree lined bank on the south side that prevents the sun from doing it's job.
No cross country ski tracks were seen on either the main trail or the unpaved trail.
