GUEST SPEAKERS:

BRENDAN HANRAHAN

Sally introduced Brendan.  He is an author, lecturer and produces documentaries on community based environmental initiatives, directs the  CT  Earth Network website, authored “Between Land and Water” on lives of  amphibians,” Exploring CT’s Natural Wonders” and “Great Day Trips in Connecticut”, has written on dinosaurs and Connecticut’s Geological background and has compiled a compendium of over five hundred environmentally based organizations, 

As an introductory remark, Brendan described the Geology of Connecticut as “Very complex in a good way” and began discussion of the influence of Geology on Cultural Landscape (ORV).

Earth Science in the New World had its beginnings here in

Connecticut. Benjamin Silliman in 1804 began training the first generation of Geologists at Yale, setting in motion a wide range of studies in

Connecticut.  Also, Connecticut was the subject of the first US Geological Survey Prominent Geologic Zones in

Connecticut. The Eastern and

Western

Highlands and central Mesozoic Rift Valley formed when the continents were stretched apart and the central valley was “ripped” open about 200 million years ago. 

Glacial history is much more recent.

JANET STONE:

 Janet is a staff member of the US Geological Survey.  She co-produced the Quaternary Geology Map of CT in 2005 and is a foremost authority on Glacial Geology.  She has led studies of glacial erosion of “softer rocks “of the deposits in the

Mesozoic

Basin over its 200,000,000 year history and the re-deposition of materials.  Janet has conducted exquisite “detective work” elucidating the glacial sequences of

Connecticut history.   Glacial depression and rebound of the land is a response to glacier withdrawal, resulting in tipping of the originally horizontally oriented glacial deposits.  The subsequent deposited alluvial (river) deposits which remain essentially horizontal have added to the complexity of interpretation of events, and has led to more thorough understanding of those events. Striations in

remnant

Highlands and the Basalt flow bedrock marking direction of glacial movement and degree of surface grinding, scouring and transport lead to interpretations of the mass and depth of the last glaciation.   Deposition in the lowlands of ground, recessional, and lateral moraine material, the formation of kames, kame terraces, kettle holes, eskers and drumlins, glacial lake deposits such as seasonally varying varved clays, damming of the glacial outflow which originally ran southward trapping the melt water in the Farmington Valley at an elevation greater than that of Lake Hitchcock in the Central Valley are all processes elucidated in her work. The opening of Tariffville gap, a fault produced at a low elevation point, which had been sealed by ice and the rapid drain down of the lake in the Farmington valley lowlands and scouring out of the Tariffville Gorge led to the creation of massive delta deposits in East Granby and Windsor in the old

Lake

Hitchcock.

When

Lake

Hitchcock broke through its dam in Rocky Hill/Cromwell and began its drain down new, prime, agricultural soils were exposed and were utilized for agriculture by the early Native Americans, following the recession of the glacier as plant and animal populations became re-established.  That prime agricultural land is in use to this day.

JELLE de BOER

Jelle is Professor Emeritus of Geology at Wesleyan where he has made great contributions to the understanding of the “hard rock” geology of the region.

Professor de Boer initiated his discussion with a brief summation of Earth history.  It is currently understood that earth formed approximately 4.5 billion years ago and led to a solid crust.  That solid state crust then retained evidence of events “recorded in stone”.

Convection currents in the liquid/semi-liquid mantle under the solidifying crust produced both vertical (upwelling and sinking currents) and horizontal (spreading currents) which applied stresses to the crust resulting in breaking the crust into plates.  Movement of these plates, pulling apart, rebounding and colliding, slipping under some and crumpling others resulted in a period of mountain building approximately 500 million years ago at the beginning of what is known as the Paleozoic Era.  Evidence points to the inference that there were three collisions of continental plates, subduction and uplift between Africa and

North America.  Approximately 380 to 350 million years ago, the Alleghenian uplift gave rise to the Appalachian Mountain system of which our Eastern and

Western

Highlands are remnants.  At about 170 million years ago there was the first opening of final separation of the continents and the formation of the

Atlantic Ocean began.

It should be noted that mountains, like icebergs have most of their mass submerged.  In the case of icebergs, the submergence is in water, in the case of mountains, that submergence is in the semi-liquid mantle under the solid crust.  Our highland mountain remnants have 30 to 50 mile deep roots.

When continents separate fracture zones develop. Two did here in Connecticut leaving a central block sinking creating our

Central

Lowlands

Mesozoic

Era

Basin.  While that block was sinking, the mountains eroded and left sediments in the lowlands making the

brownstones, etc.  characteristic of our

Central Valley.  This was in the Age of the Dinosaurs.

Folding and fracturing in the highlands associated with mountain building processes subjected deeper rocks to heating and, with release of pressure along fractures, resulted in intrusion of the melted rock (magma) along the fracture lines  If fractures reach the surface, lava flows reach the surface, such as the three basalt flows of approx 150 feet thickness each.  The

Central Lowlands are a major fault zone with numerous faults in traprock ridges

In the

Highlands hard metamorphic rocks weathered and soils were formed but were largely transported (eroded) to lowlands, therefore creating cropland zones in lowlands.

Sally asked about the rarity of an area in

Simsbury, a contact between the Paleozoic outcrop of metamorphic rocks which were formerly sea floor, subsequently lifted in mountain building and a Mesozoic basaltic lava flow in a heavily fractured zone.

This led Jelle to a discussion of geotopes which are classic examples of geologic formations or processes.  Jelle insists that geotopes should be preserved for purposes of education and that the area referred to by Sally can be considered one.

Is there uniqueness?

Janet:  We have excellent examples of glacial features and history

Sally:  Are there things which ought not to be lost?

In bedrock geology, many areas should be preserved.  In terms of glacial, activities such as sand pits etc. have revealed and contributed to understanding so their disturbance has become an asset.

 The esker in Fisher Farm is essentially a geotope.  Other excellent places in area do exist showing eskers, kettles.

NEW BUSINESS:

*1.  MAILING LIST: 

Sally discussed the concept of “sharing” mailing lists with stated restrictions and asked committee members to sign up to contact organizations.  It was also suggested that we contact historical societies for the same purpose.  The mailing list will primarily be composed of the FRWA membership list and the list of riparian land owners who were the recipients of an initial communication during the summer.

Electronic mailing lists can be directly supplied to the mailing house to avoid any other access to lists. 

There was also discussion of building an e-mailing list.  Doubt was expressed by several members as to the effectiveness of this medium as opposed to a physical publication in hand. 

*2.  LEGISLATION:

A.                            Joyce discussed a list of State Representatives and their phone numbers.  She requested that individual members sign up to contact  each legislative member to set up a meeting to discuss the bill supporting the Wild and Scenic designation and two or three other committee members to join in the actual meeting.  The legislature has convened on February 7th so the representatives should soon be available.

B.                             Joyce also reported that Eric H., Sally R. and she met with Linda Schofield who is an enthusiastic supporter and has contacted all legislators in the study area.  She also reported that Linda suggested that Joyce contact Richard Roy, House Chair of the Environment Committee. .  She reported a very successful meeting with him where he volunteered to introduce the proposed legislation to the Environment Committee.  Sally also suggested that we use any opportunity to contact local officials as well as those on the state level.  The bill has been drafted and is ready to be submitted for debate in the house sometime in February.

*3 BUDGETARY:

A.        Sally described an action taken by the committee at a previous meeting to    approve the Outreach and Education Committee’s expenditure of up to five thousand dollars ($5,000.00) for an initial mailing.

A question was raised by a committee member regarding a necessity for putting these projects out for competitive bidding. 

Eric Hammerling stated that he did not believe that we had such a requirement as long as we could demonstrate that the contractor was legitimately qualified to deliver the requisite services at a reasonable price.  Joyce indicated that she would verify this point with Jamie Fosburgh in the morning.  The committee member who raised the question said that his only concern was that we follow proper procedure within whatever guidelines are established for our fiduciary activities and not for purposes of obstruction.  Sally said that she was confident that Damon Hearne, who was involved in the Eight Mile Study, would have advised us of requirements such as competitive bidding procedures if they did exist.

      

B.     RESEARCH  PROPOSAL:

Economic Study:

The Center for Public Policy and Social Research (CPPSR) at

Central

Connecticut

State

University has submitted a detailed proposal for a multifaceted economic study of our ten town study area.  Copies of the detailed Proposal, methodology and detailed cost breakdown as well as the accompanying Curriculum Vitae of the principal researchers are available. 

Kevin Gough has reviewed the Economic Study of the

Upper Farmington and thoroughly discussed the details of the project with the principal investigators.  He stated that he is very comfortable with the value and quality of the entire proposal.  He further stated that this study will be a very valuable tool for the study area towns.  Further discussion followed.

Harry commented that there are a limited number of organizations equipped to do this study.  Eric H. also contacted the Social Inquiry group at the University of North Carolina (UNC) and the

University of

Connecticut. UNC provided a very high cost estimate but not a proposal, and the

University of

Connecticut’s Institute also gave a high estimate and a limited proposal.  Harry said that he was prepared to vote at that point.  Joyce said that CCSU was particularly eager to do the study.

Harry then moved that the Study Committee approve the expenditure and establish a contract with CPPSR at Central.  Kevin seconded the motion.  Sally asked for further discussion.  There being none, she called for a vote by show of hands indicating a readiness to vote.  Question carried with 20 yeas and one nay.

Sally then called for a vote by show of hands on the motion. 

                       There were nineteen yeas and one nay.  Motion carried.

C.     TOWN REGULATIONS COMPILATION AND REVIEW:

Eric Lukingbeal, a partner in Robinson & Cole, the firm which has offered to do the study including a pro bono matching of hours began the discussion saying that, in light of the previous discussion regarding the possible need for competitive bidding on contracts, he was perfectly amenable to delaying consideration of this project until a clarification is obtained from Jamie Fosburgh.  Eric did describe the scope and methodology of the study.

Sally proposed that a motion to proceed include the wording “in compliance with all requirements pertaining to the letting of contracts” be offered.

David Leff moved that the committee approve the award of the contract for Town Regulation Compilation and Review to the firm of

Robinson and Cole for the sum of twenty thousand dollars with the understanding that Robinson and Cole agreed to give time in similar value on a pro bono basis providing that said contract will be in full compliance with all requirements pertaining to the letting of contracts by this committee.

Motion was seconded.                      .

Vote by show of hands yielded twenty yes votes and one abstention.

Motion carried.

OTHER BUSINESS:

Joyce announced that April 26th will be the 40th anniversary of the establishment of the Wild and Scenic Rivers Act.  The Simsbury River View and Banquet Hall has offered its space for a celebratory gathering marking the event.  Further, Eric described the possibility of events marking the anniversary in each of the Study Area towns.  Beyond that, a series of river walks could be organized to introduce citizens to their own town facilities.

MOTION TO ADJOURN AT 9:37

Respectfully submitted
