----------------------------Original message---------------------------- MAGERT FIELD TRIP AT ALA ANNUAL, NYC Our field trip, organized by Alice Hudson of the New York Public Library, will be a walking tour, "Building Stones of New York City", led by Sidney Horenstein of the American Museum of Natural History. We will meet at 2:00 PM on Tuesday July 9th on the steps of the NYPL, following the General Membership meeting, which will be from 9:30 to 12:30 in the Convention Center. You can catch a #42 bus cross town to 5th Ave. There is a lovely little park (Bryant Park) next to the library for a picnic lunch (take out from a deli?) The cost will be $10. There is no need to reserve ahead, but I would appreciate an email ([log in to unmask]) if you are sure you will be coming. Here is are two excerpts from the description of the tour: "New York City, especially the island of Manhatten, is a treasure trove of building stones, a repository of materials that are imported from many regions of the world. It is also a library of dimension stone no longer being quarried". "The study and documentation of building stones are important because we see: 1. How building stones respond to the porcesses of weathering; 2. How these stones are a record of changing architectural styes; 3. How they are an important resource for students, an outdoor classroom of worldwide, stratigraphy and paleontology, including strata no longer exposed. 4. They serve as an excellent way to popularize geology." Margaret Brill Duke University MAGERT Chair
