My son Max’s science fair project this year touched on the controversial issue of deer population in urban areas. Below is a summary of his observations:
observation extends from Fletchers Boathouse to Washington Canoe Club
I stayed on the Capital Crescent Trail, while the boys fanned out between the trail and river. The deer generally coalesced in herds and then trotted in single file between us so counting them was not complicated.

Today, the Potomac Palisades Winter Olympics were held at Dino Park located between Potomac Ave and Sherier Place. Some of the action below:
During trips to sunnier climes in the North and Central America, I have noted the ubiquity of pottery sherds on the ground. Places like Tulum have a steady stream of tourist treading all over these artifacts. Sometimes it can be tricky to determine whether the sherds are from pre-columbian societies or more modern, historic times. My latest trip to Costa Rica was no different. On a casual hiking trail in Parque Santa Rosa, a mish-mash of sherds could be found alongside the trail.
The proximity to a historic finca that produced ceramic roof tiles might explain some of the sherds, but further afield in the jungle, I found this sherd jutting out of a dry-stream bank (pictured in the shaded area of the photo).
The large, undecorated sherd must have been part of an enormous pot at one time.
I took the sherd to the ranger station where they put it on display with other local curios.
I asked the rangers about the time frame of the artifacts and the indios indigenous that made them. Their response, presumambly in years, was “billiones.” Okay.

I noticed the leak yesterday afternoon while riding home on the bike path. I returned this morning after reading reports about low water pressure in the Palisades. A sizeable stream of water emerges below the historic wall at Reservoir Road and Canal Road (houses above this area are dealing with low pressure). A few words with NPS ranger and DC Dept of Environment employee suggests a water main rupture below Reservoir Road (maybe!). The water now flows into the C&O Canal and is clear. Apparently it hasn’t started to excavate. Yet.
This looks like it will be a tricky one. Get ready for the traffic snarl!
The image painted on wood pallet shows the bas-relief sandstone tablet known as the “Cincinnati Tablet” (found near downtown Cincinnati in 1841). The black portion of the painting represents the stone’s ink-stenciled areas. The grooves on the tablet’s backside suggest the stone was likely part of a tattoo kit. Other similar tablets are associated with Adena culture, 800BC – 100AD.
A good write up about the artifact, and similar Adena tablets, can be found here.
Ice Skating on the C & O Canal from Doug Dupin on Vimeo.
The low temps turned many sections between locks 4,5 solid for ice skating. I skated near the train bridge at Arizona and Canal Rd (above) and Wednesday near Chain Bridge. Yesterday, a commuter on his/her way to work on Canal Road called the police in an apparent attempt to stop somebody else’s fun. When Park Police eventually arrived, they told us (and the DC Police Officer who first arrived) that we were allowed to skate at “our own risk”. A welcomed statement since I do just about everything at “my own risk.”
Below is a video I made with a pine sapling found in the yard. I was hoping to illicit a stronger reaction from my boys. It’s certainly getting more difficult to rattle their cages!
