A Roxbury Review: Conglomerates of Greater Boston
C2-1 A ROXBURY REVIEW by Margaret D. Thompson, Department of Geosciences, Wellesley College Anne M. Grunow, Byrd Polar Research Center, Ohio State University INTRODUCTION Conglomerate throughout the Boston Basin in eastern Massachusetts (Fig. 1) has long been called after the Roxbury district of Boston (early references in Holmes, 1859 and Shaler, 1869) and subdivided into three members typified by strata in the encircling communities of Brookline, Dorchester and the Squantum section of Quincy, MA (Emerson, 1917). NEIGC field trips, beginning with one led by W.O. Crosby in 1905, and also GSA-related field trips have provided regular opportunities for generations of geologists to debate the depositional settings of all of these rocks, particularly the possible glacial origin of the Squantum "Tillite". It appears, however, that none of these outings has ever included a stop in Roxbury itself (Table I and lettered localities in Fig. 1). A main purpose of this trip will be to visit the nominal Roxbury type locality in a section of the historic quarries where recent re-development includes the newly opened Puddingstone Park. Other stops will permit comparison of type Roxbury Conglomerate with other rocks traditionally assigned to this formation and highlight geochronological and paleomagnetic data bearing on the ages of these units.

Birdobserver8.1 Page4-15 Water Birds and Shorebords in Boston
WATER BIRDS AWD SHOREBIRDS IN BOSTON HARBOR: TWENTY-SEVEN OVERLOOKS By Soheil Zendeh, Somerville and Lelf.J. Robinson, Wellesley Breeding terns and herons, clouds of migrant shorebirds, rafts of winter ing sea ducks— all may be found in Boston Harbor in season. What we call the harbor is actually the western bulge of Massachusetts Bay, a complex of islands, necks, beaches, sand bars, submerged erratics, coves, and harbors which stretches approximately 12 miles north to south and, at its widest point, 6 miles east to west. This is a guide to 27 sites, or overlooks, from which you can observe the water birds and shorebirds of Boston Harbor. The first half of this article provides a general description of the harbor, region by region, from Nahant to Quincy Bay. The southernmost portion of the harbor, Hingham Bay, will be described in a future issue. Specific directions, via public and private transport, to each overlook are grouped according to region in the second half of this article. Most places with good views of the harbor and its birds are reached relatively easily by car. Getting to the same spots via public transportation re quires, somewhat more effort but is quite feasible. With the prospect of gasoline prices doubling within the year— or gas rationing being insti tuted— urban binding, particularly by public transport, should rapidly come of age. Nahant Bay/Egg Rock Semi-circular Nahant Bay lies east of Nahant and the causeway to Lynn. Long stretches of fine white sand beaches interrupted by rocky outcrops border the bay. As you travel south and east in Nahant, the outcrops turn into high, massive cliffs overlooking the ocean. -
