arrived and became a town in the 1980s. When the railway was discontinued, its station house was purchased from the Town of Osoyoos and moved 300 m north to its current location by the Osoyoos Sailing Club. Geography Osoyoos is situated on the east-west Crowsnest Highway (Highway 3) with a significant ascent out of the Okanagan Valley in either direction. The Crowsnest headed east begins with an switchback up the flank of the Okanagan Highland with a rise to the mining and ranching region of Anarchist Mountain, which is part of the Boundary Country (the stretch of rising highway is also referred to as Anarchist Mountain). Highway 3 westbound leads to Keremeos and the Similkameen Valley via Richter Pass. On Highway 97 south is a 24-hour border crossing between Canada and the United States between Osoyoos and Oroville, Washington. The Canada–United States border is located south of the Highway 3 and 97 intersection on the northwest side of town. The town is situated on Osoyoos Lake, which has a perimeter of , an elevation of , a maximum depth of , and a mean depth of . The lake’s elevation marks the lowest point in Canada of the Okanagan Valley. Ecology The far southern reaches of the Okanagan and Similkameen Valleys are part of a threatened xeric shrubland ecosystem in Canada known as the Columbia Plateau ecoregion. Specifically, the ecosystem of the area is named after the antelope brush plant typical of the local climate. This ecosystem was once more prevalent in the South Okanagan but is now becoming fragmented and degraded due to the spread of agriculture, urban development, and other human activities. Since 2003, a feasibility study by Parks Canada has been going on to determine the need for protection of a large area of grasslands west of the town known as the South Okanagan-Lower Similkameen National Park Reserve Feasibility Study. Climate The climate, according to the Köppen climate classification, is a cold semi-arid (BSk) with summers that are generally hot and dry. Although it claims to be a desert, Osoyoos is actually about too wet to be an actual desert. The average daytime temperature in Osoyoos is , which is the warmest in Canada. Osoyoos also has an average annual temperature of , which is one of the warmest in the country. September and October are usually dry and sunny with cool mornings. Winters are short and
