Cistern Project at Blake Garden

Thursday, April 30th, 2009

During the month of April work has been done to repair a leak in the 1500 gallon cistern in Australian Hollow. The cistern was initially acquired by the garden in the mid 1970’s during a drought and hooked up – at that time – to the seep under the parking structure.

PHD candidate Kristen Podolak, LAEP graduate student Nathan Hodges, volunteer Peter Suchecki, and three students from ES 125 (May, Austin and Linda) fixed the leak and built a new foundation out of recycled sidewalk cement (donated by Mike Frappier) for the cistern. A zip line was rigged from the event lawn area to get the heavy cement blocks and mulch down to the cistern area.

This past Monday the bamboo aqueduct that brings the water from the seep was hooked up to the cistern and it is filling once again. The garden is exploring solar pumping options to transport the water to other parts of the garden.

Lawn Bench Project

The bench project is moving along. The LAEP students have dug the holes and poured the concrete footings for the bench. They also have started to cut and fit the 2” recycled redwood that will serve as the seating of the bench.

Park Day School Field Trip

Thursday, April 30th, 2009

On april 24th, Amida Cary, Kindergarten Teacher from Park Day School brought her class to the garden for the morning. They are studying California native plants. We went on a tour of the garden looking for some of the gardens best examples of native plants: Coastal Redwoods in the redwood grove, Coast Live Oak and manzanita in the Mediterranean area of the garden, and of course, California poppies are popping up everywhere in the garden. We each made a drawing of poppies from a leaf rubbing of dried poppy leaves. The students went over the parts of the plants and then we all got to plant a California Poppy plant in a meadow area of the garden. They finished their visit by creating in the Create with Nature Zone.

EPS 50 Geology class visits Blake Garden

Sunday, April 26th, 2009

On April 24th, UC Berkeley Professor Chi Wang brought his EPS 50 geology class to the garden as part of a tour of Bay area geology. He met with his students at  the 30′ blue schist outcropping in the lower part of the garden. They discussed the index minerals that are found in the large rock: Lawsonite and Glauconite. Lawsonite is named for UC Geology Professor Andrew Lawson (1861-1952), although it was actually discovered by one of his students, who named the mineral in his honor.

Course desciption for EPS 50:
An introduction to the physical and chemical processes that have shaped the earth through time, with emphasis on the theory of plate tectonics. Laboratory work will involve the practical study of minerals, rocks, and geologic maps and exercises on geological processes.
