In his role as Utility Control as part of Malloy’s effort to citizen-volunteer, Steve was one of the great forces streamline government and shrink the state budget. who helped ensure that Connecticut would have this (continued on page 4) wilderness park; he was also a founder and vice- president of this Park Association. Steve, his wife Barrie, and their colleagues are a wonderful example of Margaret Mead’s wise observation: “Never doubt that a small group of thoughtful, committed people can change the world. Indeed, it is the only thing that ever has.” West Rock Ridge State Park is one of Steve’s many beautiful legacies. As you will read in the following pages, the Park is enjoyed by birds and birders, rare butterflies and lepidopterists, schoolchildren and professors, bicyclists, runners, and walkers, and is a joyful venue for Earth Day celebrations and energetic fundraisers to support environmental organizations, Habitat for Humanity and LiveStrong. Join in some of these events, and Summit Highlights enjoy the park on your own.

Information and registration: http://fairfieldwestchesterlivestrong.weebly.com/911---rock-the-ridge-mtb-race--ride.html 2 Rock to Rock is a day-long celebration of Earth Day and of New Haven’s rich environmental and cultural resources. Cyclists will travel from West Rock to East Rock, with celebrations on both sides of the city. Along the way eat tasty food, hear great music, take on environmental service projects, explore Edgewood and Beaver Ponds Parks, and ride a portion of the Farmington Canal Trail and official city bike lanes. Hard core riders can take detours to the summits of the two rocks or a longer route that connects West Rock, Sleeping Giant and East Rock. You can ride as an individual or create your own team. You can also help raise funds for one or more of 13 environmental organizations: including Solar Youth, New Haven Land Trust, Urban Resources Initiative, Common Ground High School, New Haven Parks Dept., CT Fund for the Environment and others. To register, go to: www.firstgiving.com/register.php. The route officially begins at Common Ground, 358 Springside Ave., New Haven at the base of West Rock Ridge State Park and finishes at College Woods at East Rock Park. The eight-mile route was plotted with all ages and abilities in mind. It is flat, safe and fun and makes use of many of the city’s best cycling resources. A suggested short route starts at Common Ground and goes only to Edgewood Park or Beaver Pond Park and returns to the starting point. Two years ago there were 250 riders and they raised $10,000. Last year there were 350 riders and $20,000 was raised. This year the hope is that 500 riders will participate and raise $40,000. Advance adult registration is $25, or $30 on the day of the event. Youths 18 and under can register for $15. For info: www.rocktorock.org. 9:00-10:30 - Registration, breakfast, and entertainment at Common Ground High School. 358 Springside Avenue, New Haven.

  • Heroes Tunnel Project Route 15 Wilbur Cross Parkway State Project No
    HEROES TUNNEL PROJECT ROUTE 15 WILBUR CROSS PARKWAY STATE PROJECT NO. 167-108 PURPOSE AND NEED STATEMENT (Revised 7/3/18) PROJECT CONTEXT The Heroes Tunnel is located along the Wilbur Cross Parkway (Route 15) in the Town of Woodbridge and the City of New Haven, near the Town of Hamden border. The Heroes Tunnel is a 1,200-foot long tunnel, which passes through West Rock Ridge in New Haven and Woodbridge. The existing tunnel was constructed between spring 1948 and fall 1949 and consists of two 28-foot wide by 19-foot high barrels with horseshoe cross-sections. The northbound and southbound barrels of the tunnel consist of two 11-foot wide travel lanes with 6-inch shoulders and a 2-foot 6-inch wide raised maintenance walk on each side. The centerlines of the barrels are approximately 63 feet apart. It is the only tunnel to pass beneath a natural land feature in the State of Connecticut and is eligible for listing on both the National and State Registers of Historic Places. The Heroes Tunnel Project limits encompass the 1,200-foot tunnel and extend approximately 2,000 feet from the tunnel portals, in both the northbound and southbound directions, as illustrated in Figure 1 attached. EXISTING TRANSPORTATION NETWORK The Wilbur Cross Parkway is a limited access highway, classified as an urban principal arterial – other expressway, comprising a portion of Route 15 between Milford and Meriden where commercial vehicles, trailers, towed vehicles and buses are prohibited. As a continuation of the Merritt Parkway in Fairfield County, Route 15 is an important route between the New York City metropolitan area and central Connecticut.

  • Land, Natural Resources, and Geology
    Land and Natural Resources of West Amwell By Fred Bowers, Ph.D Goat Hill from the north Diabase Boulders are common. Shale and Argillite outcrops appear like this. General Description of the Area West Amwell Township is in Hunterdon County, New Jersey, USA. It is a 22 square mile rural township with just over 2200 people, located near Lambertville, New Jersey. It is one of the more scenic parts of the New Jersey Piedmont. It is identified in red on the maps below. West Amwell is characterized by most people as a "rocky land." One of the oldest villages in the township is called Rocktown. If you visit or look around the township, you cannot avoid seeing rocks and outcrops like those pictured above. Hunterdon County New Jersey, with West Amwell located at the southern border, marked in red The physiographic provinces of New Jersey, with Hunterdon County and West Amwell marked in red Rocks The backbone of West Amwell Township's land is the Sourland Mountain; a typical Piedmont ridge formed by a very hard igneous rock called diabase or "Trap Rock." The Sourland Mountain ends at the Delaware River below Goat Hill which you see in the picture above, looking south from the Lambertville toll bridge. To the south and north of the diabase, shale and argillite occurs, and these rocks form the lower lands we know of as Pleasant Valley and the shale ridges and valleys you see from around Mt. Airy. In order to appreciate the rocks and the influence they have on the look of the land, it is useful to have a short review of rocks.

Its Late Permian–Middle Triassic section includes basaltic stratum-like bodies, sills, formed at 250–248 Ma. The basalts are medium-high-Ti tholeiites enriched in La. Compositionally they are close to the Early Triassic basalts of the Syverma Formation in the Siberian Flood basalt large igneous province, basalts of the Urengoi Rift in the West Siberian Basin and to the Triassic basalts of the North-Mongolian rift system. The basalts probably formed in relation to mantle plume activity: they are enriched in light rare-earth elements (LREE; Lan = 90–115, La/Smn = 2.4–2.6) but relatively depleted in Nb (Nb/Labse = 0.34–0.48). Low to medium differentiation of heavy rare-earth elements (HREE; Gd/Ybn = 1.4–1.7) suggests a spinel facies mantle source for basaltic melts.

Instead, rocks in some parts of the lower crust and/or upper mantle need to melt in order to make magma. Once magma forms, it will try to rise from higher-pressure regions (deeper in the crust) to lower pressure areas (near Earth’s surface) because magma is less dense than solid rock. As magma rises, it cools. Most often, it cools and hardens (the magma crystallizes, meaning that crystals [minerals] form) before it makes it to the surface. But sometimes magma will migrate all the way to Earth’s surface and erupt in a volcano. Once it erupts, the magma is called lava.

  • West Rock Ridge State Park Is 35 Years Old This Summer! 1975 - 2010
    Newsletter of the West Rock Ridge Park Association Spring 2010 West Rock Ridge State Park is 35 years old this summer! 1975 - 2010 FROM THE PRESIDENT: The Good, the Not so Bad, and the Beautiful The Good (actually, The Great): Thanks to a grant from the George Dudley Seymour Foundation, and to the perseverance, hard work, and dedication of Beth Brothers, Assistant Director of Land Acquisition and Management Division for the CT Dept. of Environmental Protection, the State was able to purchase a critical parcel for our park. The approximately 12-acre property, which fronts on Mountain Road in Hamden and extends up to the Blue Trail and the ridge, has been a Priority 1 acquisition since the park’s inception in the 1970's. We are extremely grateful to Beth and to the George Dudley Seymour Foundation for making this important acquisition possible. The Not so Bad: As you may know, in response to the current fiscal difficulties, last October the State had doubled most fees at state parks. While this legislation did not directly affect West Rock, since our park has no fees, it affected all of the other state parks, which many of us know and love. Representatives from all the Friends of CT Parks groups gathered at the Capitol building in March to highlight all the great activities in our state parks, and to urge lawmakers to “Ease the Fees, Please.” Now, thanks to a successful grass roots mobilization by all of the Friends groups, the Governor has signed the Deficit Mitigation bill, which includes a provision to reduce the fees at state parks.

Fritts New data concerning the geologic structure, stratigraphy, petrography, origin, and ages of bedrock formations in an area of approximately 111-square miles in south-central Connecticut were obtained in the course of detailed geologic mapping from 1957 to 1960. tapping was done at a scale of 1:24,000 on topographic base maps having a 10-foot contour interval. Bedrock formations are classified in two principal categories. The first includes metasedimentary, meta-igneous, and igneous rocks / / of Precambrian to Devonian age, which crop out in the western parts of both quadrangles. The second includes sedimentary and igneous i/ \s rocks of the Newark Group of Late Triassic age, which crop out in the eastern parts of the quadrangles. Diabase dikes, which are Late Triassic or younger in age, intruded rocks in both the western and eastern parts of the map area. Rocks in the western part of the area underwent progressive regional metamorphism in Middle to Late Devonian time. The arrange­ ment of the chlorite, garnet, biotite, staurolite, and kyanite zones here is approximately the mirror-image of metamorphic zones in Dutchess County, New York. However, garnet appeared before biotite in pelitic rocks in the map area, because the ratio MgO/FeO is low. / / Waterbury Gneiss and the intrusive Woodtick Gneiss are parts of « ,/ a basement complex of Precambrian age, which forms the core of the i Waterbury dome.
