Denali Drilling began taking core samples today. When I arrived on Oceanview Drive at approximately 3 PM, drilling had reached about 15 feet. The core sample was very watery. (That is definitely not a technical description!) I understand that the drill subsequently encountered a substantial clay layer. Drilling will take place in the affected area as well as on Barnett Road, above the affected area.
Additionally, a survey crew set reflectors on a targeted utility pole to enable equipment to register accurate movement of the affected area. Borough Water & Sewer employees Scott Bradford and Dennis Durr mounted the reflectors on the Oceanveiw Road utility pole guided by the surveyors communicating by radio from their position on Front Street.

Today's update, posted on the Borough website at 3 PM states:
Denali Drilling from Anchorage began drilling test holes around noon today, starting on Ocean View Drive. They will be drilling a series of holes above and below the slump area to provide PND Geologists and Engineers with soil samples of the area. Borough Sewer & Water employees worked with PND engineers set up control stations to collect accurate measurements of the movement in the active slide zone, as well as data of the area above the “cracks” of the active portion of the slump. Work will continue Thursday & Friday, with a planned lane closure for drilling in Lutak Road on Friday morning.
The recent storm hindered the mechanical measurements of the movement over the last 24 hours, but the activity we could see where the snow was plowed out for the drilling crew appeared to be about the same; from 1 –2 inches.
