The NHD is a national framework for assigning reach addresses to water-related entities, such as industrial discharges, drinking water supplies, fish habitat areas, wild and scenic rivers. Reach addresses establish the locations of these entities relative to one another within the NHD surface water drainage network, much like addresses on streets. Once linked to the NHD by their reach addresses, the upstream/downstream relationships of these water-related entities--and any associated information about them--can be analyzed using software tools ranging from spreadsheets to geographic information systems (GIS). GIS can also be used to combine NHD-based network analysis with other data layers, such as soils, land use and population, to help understand and display their respective effects upon one another. Furthermore, because the NHD provides a nationally consistent framework for addressing and analysis, water-related information linked to reach addresses by one organization (national, state, local) can be shared with other organizations and easily integrated into many different types of applications to the benefit of all. This dataset represents NHD as published by USGS on 4/27/2019.

NCED is currently involved in researching the effectiveness of anaglyph maps in the classroom and are working with educators and scientists to interpret various Earth-surface processes. Based on the findings of the research, various activities and interpretive information will be developed and available for educators to use in their classrooms. Keep checking back with this website because activities and maps are always being updated. We believe that anaglyph maps are an important tool in helping students see the world and are working to further develop materials and activities to support educators in their use of the maps.

This website has various 3-D maps and supporting materials that are available for download. Maps can be printed, viewed on computer monitors, or projected on to screens for larger audiences. Keep an eye on our website for more maps, activities and new information. Let us know how you use anaglyph maps in your classroom. Email any ideas or activities you have to ncedmaps@umn.edu

Anaglyph paper maps are a cost effective offshoot of the GeoWall Project. Geowall is a high end visualization tool developed for use in the University of Minnesota's Geology and Geophysics Department. Because of its effectiveness it has been expanded to 300 institutions across the United States. GeoWall projects 3-D images and allows students to see 3-D representations but is limited because of the technology. Paper maps are a cost effective solution that allows anaglyph technology to be used in classroom and field-based applications.

Maps are best when viewed with RED/CYAN anaglyph glasses!

The bedrock geology of the Bellows Falls 7.5 x 15 minute quadrangle, Vermont and New Hampshire, consists of polydeformed Ordovician to Devonian metasedimentary, metavolcanic, and metaplutonic rocks of the Connecticut Valley trough, Bronson Hill anticlinorium (or Bronson Hill terrane), and the Central Maine terrane. Previous work in this area includes a 1:62,500-scale published map and text by Kruger (1946), state geologic maps of New Hampshire (Lyons and others, 1997) and Vermont (Ratcliffe and others, 2011), and various maps and reports presented largely as parts of field trip guidebooks (e.g., Thompson and Rosenfeld, 1979; Chamberlain and others, 1988; Spear, 1992; Thompson and others, 1993). Armstrong (1997) completed a provisional open-file map of the geology of the Vermont part of the Bellows Falls 7.5 x 15 minute quadrangle, which is incorporated and revised on this map based on additional field work. This study recognizes three major structural levels from west to east, lowest to highest: (1) autochthonous rocks of the Connecticut Valley trough (CVT); (2) allochthonous rocks of the New Hampshire sequence and Bronson Hill arc in the Monroe thrust sheet, including the Skitchewaug nappe; and (3) allochthonous rocks of the Fall Mountain thrust sheet or nappe. The CVT consists of metasedimentary and metavolcanic rocks of Devonian Gile Mountain and Waits River formations, which are located west of, and within splays of the Westminster West fault zone. The CVT rocks are largely greenschist facies with most rocks in the biotite to garnet zones. The Monroe thrust sheet carries transported New Hampshire sequence, and include rocks previously described as the Cornish and Skitchewaug nappes (Thompson and others, 1968), and now interpreted to be largely at the same structural level (Walsh and others, in press). These rocks reached greenschist to amphibolite facies, with the lower biotite grade rocks occurring to the west near the Connecticut River. The eastern side of the CVT and the western side of the Skitchewaug nappe are dissected and deformed by multiple strands of the sinistral Westminster-West fault (Armstrong, 1997; McWilliams and others, 2013), an Alleghanian structure. The largest strand is marked by a significant zone of phyllonites—derived from various adjacent rock types from within the CVT—and chlorite grade retrogression. In the fault zone west of the Connecticut River, higher grade metamorphic assemblages are retrograded, deformed, and truncated in this wide zone. The Skitchewaug nappe shows an internal west-to-east increase in metamorphic grade from garnet zone to staurolite zone to sillimanite + muscovite zone near the Alstead dome. The Skitchewaug nappe exposes Ordovician to Devonian rocks of the New Hampshire sequence: Ordovician Partridge Formation, Silurian Clough Quartzite, Silurian Fitch Formation, and Devonian Littleton Formation. The Alstead dome is cored by Ordovician Ammonoosuc Volcanics and intruded by Oliverian Plutonic Suite trondhjemitic to granitic gneisses. The Ammonoosuc Volcanics is comprised of various amphibolites and hornblende schists. A metatuff mapped at the top of the Ammonoosuc Volcanics along the western flank of the dome yielded a Sensitive High Resolution Ion Microprobe (SHRIMP) U-Pb zircon crystallization ages of 455 ± 11 (Merschat and others, 2015; Valley and others, 2015, in press). Gneisses of the Oliverian Plutonic Suite are separated into two bodies: a smaller body to the north (~1.5 km long) and larger body extending southward beyond the quadrangle border. SHRIMP U-Pb zircon crystallization ages from these bodies are 448 ± 7 Ma and 452 ± 6 Ma, respectively (Merschat and others, 2015; Valley and others, 2015, in press). Map-scale truncations, a metamorphic break (staurolite against biotite and garnet zones), and mylonitic fabrics indicate a fault along the west side of the Skitchewaug nappe, which is mapped as the Northey Hill thrust. The structurally highest nappe, Fall Mountain, is floored by the Brennan Hill thrust (BHT) and contains sillimanite zone and higher-grade Silurian Rangeley Formation intruded by the ~400 Ma Bethlehem Granodiorite (Merschat and others, 2015). The BHT truncates units of the Skitchewaug nappe and juxtaposes the Bethlehem Granodiorite and migmatitic, sillimanite + K-feldspar zone Rangeley Formation over staurolite zone rocks of the Skitchewaug nappe. Reduction in grain size and an increase in the amount of biotite and muscovite in the Bethlehem Gneiss occur near the BHT. Mineral lineations plunge southeast, and kinematic indicators and fold patterns support NW-directed transport. The Fall Mountain nappe may be a west-directed sheath fold, similar to the Skitchewaug nappe and other F1-nappe stage folds (Walsh and others, in press). 40Ar/39Ar muscovite and amphibole ages across the nappes suggest Devonian to Mississippian cooling of the Bronson Hill anticlinorium. Amphibole from the Skitchewaug nappe in a window through the Fall Mountain nappe yields the oldest age at ~380 Ma, while amphibole age spectra from the Alstead dome yield ages of ~330 Ma. Muscovite ages from the Fall Mountain nappe and the Littleton Formation in the Monroe nappe in Vermont yield ages of 316-335 Ma, while ages near the Alstead dome are younger, ~300 Ma. Collectively, the 40Ar/39Ar data suggest peak metamorphism in the Skitchewaug nappe prior to ~380 Ma followed by emplacement of the FM between 335–380 Ma. The Alstead dome may have formed at ~330 Ma or later, and local late fabrics and younger muscovite ages are probably related to late Alleghanian sinistral tectonics. 40Ar/39Ar muscovite ages from the Westminster-West fault zone indicate it is a sinistral Alleghanian fault at ~300 Ma (McWilliams et al., 2013). Extensional Mesozoic faults cut all structural levels. Mesozoic faults have normal dip-slip and strike-slip kinematics. Apatite fission track (AFT) data indicate that the brittle Ammonoosuc fault was active prior to about 100 Ma and experienced little to no re-activation in the Cretaceous, but other regionally significant older ductile faults such as the Northey Hill experienced late Cretaceous (less then 80 Ma) re-activation (Roden-Tice and others, 2009). Additional AFT data suggest some Cretaceous activity on regional brittle faults like the Grantham fault may have extended into the Paleocene (Schnalzer and others, 2015). Extensive brittle faults and slickensided foliation surfaces in the vicinity of the Westminster-West fault zone, especially along Interstate 91, attest to Mesozoic re-activation of earlier structures.

This map is to help people locate LiDAR-derived 2-ft contour data sets in New Hampshire. Both HUC 8 and HUC 10 units are displayed along with the HUC labels so that users can find which contour service covers their area of interest. For services residing on ArcGIS Online, contour services are available by HUC 10. HUC 8 services (including HUC 10 sub layers) are available in the EDP folder on nhgeodata.unh.edu/nhgeodata/rest/services.

This data set represents smoothed, 2-foot bare earth contours (isolines) for the Lower Androscoggin (01040002) HUC 8 unit. It was derived from a data set which was compiled from LIDAR collections in NH available as of spring, 2019. The raster was filtered using the ArcGIS FOCAL STATISTICS tool with a 3x3 circular neighborhood. The contours were generated using the ArcGIS CONTOUR tool while applying a Z factor of 3.2808 to convert the elevation values from meters to feet. The filtered contours were then smoothed using the ArcGIS SMOOTH LINE tool. The data include an INDEX field with values of 10 and 100 to flag 10 and 100-foot contours. When viewed using this service, contours become visible at scales greater than 1:10,000.

The database contains predicted sea level rise extent layers and baseline layers for the open coast of New Hampshire, the Piscataqua River, and Great Bay based on 2019/2020 LiDAR elevation data.Data comprise the following eleven scenarios:p_MHHW_1_foot_slr: Mean higher high water + 1' sea level risep_MHHW_2_foot_slr: Mean higher high water + 2' sea level risep_MHHW_4_foot_slr: Mean higher high water + 4' sea level risep_MHHW_6_foot_slr: Mean higher high water + 6' sea level risep_MHHW_8_foot_slr: Mean higher high water + 8' sea level risep_MHHW_baseline: baseline elevations from which the MHHW sea level rise layers were derivedp_MHHW_FLOOD_2_foot_slr: Mean higher high water + one percent annual chance flood + 2' sea level risep_MHHW_FLOOD_4_foot_slr: Mean higher high water + one percent annual chance flood + 4' sea level risep_MHHW_FLOOD_6_foot_slr: Mean higher high water + one percent annual chance flood + 6' sea level risep_MHHW_FLOOD_8_foot_slr: Mean higher high water + one percent annual chance flood + 8' sea level risep_MHHW_FLOOD_baseline: baseline elevations from which the MHHW_FLOOD sea level rise layers were derivedThe four data layers that incorporate the 100-year flood are based on the April 2014 preliminary Digital Flood Insurance Rate Maps (DFIRMs) for Rockingham and Strafford Counties.

This dataset combines the work of several different projects to create a seamless data set for the contiguous United States. Data from four regional Gap Analysis Projects and the LANDFIRE project were combined to make this dataset. In the northwestern United States (Idaho, Oregon, Montana, Washington and Wyoming) data in this map came from the Northwest Gap Analysis Project. In the southwestern United States (Colorado, Arizona, Nevada, New Mexico, and Utah) data used in this map came from the Southwest Gap Analysis Project. The data for Alabama, Florida, Georgia, Kentucky, North Carolina, South Carolina, Mississippi, Tennessee, and Virginia came from the Southeast Gap Analysis Project and the California data was generated by the updated California Gap land cover project. The Hawaii Gap Analysis project provided the data for Hawaii. In areas of the county (central U.S., Northeast, Alaska) that have not yet been covered by a regional Gap Analysis Project, data from the Landfire project was used. Similarities in the methods used by these projects made possible the combining of the data they derived into one seamless coverage. They all used multi-season satellite imagery (Landsat ETM+) from 1999-2001 in conjunction with digital elevation model (DEM) derived datasets (e.g. elevation, landform) to model natural and semi-natural vegetation. Vegetation classes were drawn from NatureServe's Ecological System Classification (Comer et al. 2003) or classes developed by the Hawaii Gap project. Additionally, all of the projects included land use classes that were employed to describe areas where natural vegetation has been altered. In many areas of the country these classes were derived from the National Land Cover Dataset (NLCD). For the majority of classes and, in most areas of the country, a decision tree classifier was used to discriminate ecological system types. In some areas of the country, more manual techniques were used to discriminate small patch systems and systems not distinguishable through topography. The data contains multiple levels of thematic detail. At the most detailed level natural vegetation is represented by NatureServe's Ecological System classification (or in Hawaii the Hawaii GAP classification). These most detailed classifications have been crosswalked to the five highest levels of the National Vegetation Classification (NVC), Class, Subclass, Formation, Division and Macrogroup.
