McNabs Island is located at the mouth of Halifax Harbor and has an area of ​​approximately 395 hectares. On McNabs Island, the highest elevation is 45 meters. The elevation of this island rises towards the middle, so the central land elevation is higher than the edge. Additionally, the proportion of flat areas is around 20%, most of which are found on hilltops and coastal beaches. The proportion of gentle and moderate slopes is about 25%, and most of them are in the middle zone of the island; the proportion of steep slopes is around 30% and is located near and along the coasts. Additionally, from the slope and elevation map we made before, we can see that the coastline has a lower elevation with steep slopes or flat lands. The cliffs are the steepest places and most are close to the coast. They always have a higher elevation with the shortest intervals between contour lines. The flat areas of the coastline are mainly around beaches, ponds and wetlands. The valleys are always found in gently or moderately sloping areas with different altitudes. There are three types of structural materials present on McNabs Island. First, the bedrock which is the slate of the Halifax Formation is approximately 70 percent covered, and the remainder is covered by quartzite and graywacke of the Goldenville Formation. Additionally, McNabs is primarily made up of glacial deposits such as drumlins, and there are some alluvial, shoreline marine, lake and coastal sediments. For the soil type of the land, it is mostly covered with Wolfville soil, and this soil type still has good drainage with light to moderate erosion. For the hydrology of the island, there are several wetlands, ponds and streams spread throughout. The major watershed divisions of the McNabs are primarily composed of about 80 percent non-dominant species, and about 10 percent spruce, 4 percent red maple and intolerant hardwoods, and about 2 percent. percent balsam fir. Overall, there are some land uses on McNabs Island. Certain cultural characteristics appear. An example of cultural features on McNabs Island is the Maugers Beach Lighthouse, located on the mid-west end. This lighthouse sits on the lower lands and is used to observe the surroundings and help ships see at night. Additionally, some forts were built in the past to overlook the harbor entrance. Since McNabs Island is now open to the public, certain roads and trails allow people to visit the land. Additionally, there are several buildings on the island, but almost all of them have been demolished due to their poor condition and the cost of maintaining them (Nova Scotia Department of Natural Resources, 2005).
