Work Against the Machine

We await new construction at the Palisades Rec Center in DC starting perhaps today Monday, July 11, 2017.   Items from this area recovered yesterday.

Two examples of fire-cracked rock here.  Ultimately, I found nothing of particular interest.

I eventually dug down about 4 feet, only to uncover a cast iron sewage/storm pipe.  My choice of digging site coincided with an already trenched portion of the park.  The area destined to house the new Rec Center indeed appears to be heavily disturbed earth.  I will closely monitor the excavation in the coming weeks.

Hawaiian Chunkey Stones

I never heard of the Hawaiian bowling stones known as maika until I saw these artifacts in the Kokee Natural History Museum in Waimea Canyon, Kauai.   With the same appearance as mainland chunkey stones, the ulu maika game apparently differed by not using the rolling stones as targets.

Blooming White in the Garden

I often notice flowers of different species will bloom simultaneously in matching colors.   In the garden right now, it’s white’s turn.

From top to bottom:  taro, cilantro, waterlilly

Suspicious Squirrel Deaths

Yesterday, I noticed a dead squirrel at the base of a sycamore tree in my yard.  I’ve seen plenty of squirrels fall out of trees only to bounce off the ground like rubber balls and go about their business so this squirrel, with no visible trauma, posed a mystery.    This morning I noticed another lifeless squirrel half emerged from the giant weaver’s nest in a different sycamore tree in the yard.   Perhaps a squirrel plague has arrived???

Latest Works of Art

Here are three pieces I recently completed.

Above is a modified print produced by Frances Lubben.  I left the mountains (middle section) while painting in the upper section the night sky and lower section a glacial lake.   The constellation of Havoc, the wild dog of NW DC, is another stab at building the dog legend.  The frame I built from flooring (the bottom grooved side) and attached wasp nest paper.

I recently added red coral to my braided water-iris piece with opihi shells.   The coral was in a “gift box”  of different beach taxonomy.  I had never seen such striking red and wanted to produce as many wafers from the clump of scarlet coral as I could – enough to line the two borders.  The pieces are fixed to rods protruding from the back board.

The above sculpture is a series of die casts used for threading pipe.  Magnets keep the steel together and help mount it to a block of wood.

Impressions on Prehistoric Pottery

Below is a sherd brought to me by a neighbor.

I’ve seen these tight striations before (the two parallel patterns) and had always assumed it was a cord (only) that produced such impressions.  However, the zig-zag of 90 degrees suggests that a stick? with perhaps cord tightly spooled, created these designs.

Those 130,000 Years Old Californians

Big archeo news with the publication of a Nature article claiming that hominids butchered a Mastodon 130,000 years ago in what is now San Diego, CA.   It’s a huge anomaly since the generally accepted date for humans in the Americas is around 15,000 years ago.   I think this might be another case of animals adopting tool-use behavior (like monkeys in South America).   Elephants have been observed using rocks and sticks for various tasks.   Could this be the case of an exceptionally pissed off Mastodon hammering the remains of a dead rival?  Dunno.

Happening Today

I just returned from the Kennedy Center expansion site along the Potomac River this morning and got to see a construction team of amigos digging up the old ground surface (well below fill).  You can see the rich soil being dug up to build foundations for the subterranean parking garage.

I hope somebody from the National Park Service might see what is being dug up there.

 

My previous post comments on this development.

More Archeo Obliteration along the Potomac in DC

I keep thinking that development along the Potomac River in Washington DC has all but erased the archeological record, but said development continues to gobble up little untouched portions.  The latest is the Kennedy Center’s expansion along the banks of the Potomac River.   This is a big project and thus required an environmental/cultural impact study.   The “Preservation and Historical” consultant for the expansion project is listed as Robinson and Associates, but the work seems to have been carried out by Stantec (subcontracting subcontractors is a great method to avoid accountability!).   Stantec’s Phase 1 Archeological Investigation stated the obvious in its conclusion – “Given that the terrestrial portion of the Kennedy Center Expansion project APE has a high potential for Native American and Historic period resources, and that there is a potential that fill has capped and protected those resources, additional archaeological investigations are warranted if final plans for the proposed project indicate excavations will continue below the currently documented depths of fill.”

The so called “geoarcheo boring measurements” provided by Langan Environmental and Engineering Services, Inc. suggested the fill ranged on the site between 19 – 29 ft.  In a report presented by the NPS/National Capital Planning Commission the impact on archeological resources is negligent because:

  • GIS elevation change modelling and geotechnical borings indicate:
    • 19 feet or more fill along west and south portions of project area
    • 29 feet along I-66
  • Construction plans indicate removal of:
    • 18 feet or more along west and south portions of project area
    • 28 feet along I-66
    • Conclusions  About 1 foot of fill could protect any resources potentially present

Here are the incredible coincidences that apparently spared the archeological record of the expansion project.

Note the underground garage that presumably does not cross those thresholds.

You can see a time-lapse of the excavation here.

I wonder about the incentives for archeological non-discoveries.   Obviously, an archeological firm that has a track record of finding nothing would be much sought after by developers.  This fact, coupled with the tacit approval of government agencies (DCHPO, NCPC, NPS)  leaves little chance for archeological discovery.
