Click on the numbers to see the image, in a 640x480 pop-up window. These were taken with a Philips model-675 webcam, with 640x480 resolution, and a Linux laptop. Sorry about the focus and exposures, I'm not much of a photographer.
This is construction going on, at "Norbeck Road Extended". The low area directly ahead in the first image is one of the tributaries of the Northwest Branch of the Anacostia River. This is, believe it or not, considered one of the finer trout streams in the State of Maryland. The water is generally quite clear.
1. Looking roughly east along Norbeck Road (MD Route 28) about 150 meters west of the intersection of Norbeck and Layhill. This is a composite shot to get a panoramic effect.
2. Looking to the North more or less, across Norbeck, at a storm-water catch-basin. Beyond it is the tributary of the Northwest Branch.
3. Here is a view which goes just a bit to the right. You can orient this to the previous photo with the large evergreen tree to the right of the previous photo. Please note that the intersection is well-elevated above the natural stream-bed.
4. From nearly the southwest corner of the intersection, looking roughly east. At roughly the center of the picture, see what appears to be a future road-bed. Please note the concrete structure barely visible beneath the cable dangling from the crane.
5. Looking roughly North again, towards the same concrete structure, from a bit to the right of the edge of the previous image. Please note the boulders edging the right side of the streambed. Note also the large plastic pipe, which is the outflow from a sediment filtration system. Please note on the left that there is a runoff-barrier, vertical, of black plastic, and a space between that and the concrete structure.
6. Here's another view of the filtration outflow pipe. Please notice the clarity of the stream.
7. Getting a bit closer, and looking between the vertical plastic-sheeting runoff-barrier and the concrete structure, here is lovely tributary of the Northwest Branch of the Anacostia River being temporarily diverted through a plastic-sheeted ditch. The plastic sheeting prevents erosion of the banks of the temporary stream-bed, in effect the stream is flowing through a channel in a giant sandbag.
8. Here's another view. Note the outflow pipe in the right side of the image. Apparently the concrete structure is a bridge footing.
9. Standing at about the same place as in image "5", but looking the exact opposite direction, roughly South along Layhill Road. The stream-bed is on the left.
10. Looking roughly Northwest, standing on the old roadbed. You can see that the temporary stream channel is just beyond that runoff-barrier sheeting. This area used to be prone to flash-floods during summer storms.
11. Taken from just beyond the white crane in the previous image, looking roughly East from the edge of Layhill Road, just north of the intersection.
12. Sorry, I couldn't do anything about the traffic... This is looking roughly Northwest along the streambed. Note the gently rollong landscape. This tributary drains a fair swath of land.
13. From roughly the same vantage, but looking a bit more northerly. The yellow structure is at the intersection with Dr. Byrd Road, I believe. At any rate, if you took a left there, you'd wind up eventually running into MD Route 108 near Batchellor's Forest Road. All of that land clear in to Olney is drained by this little stream. As I said, when it rains, this commonly would flood.
14. I believe this speaks for itself. Copyright 2001, by yours truly.
More (uncommented) images are available here, which are of other construction on "Maryland Route 28 Extended -- Norwood Road", and also of other scenes on or near proposed InterCounty Connector rights-of-way.
