Giant homegrown vegetables and the headquarters of the best-known dogsled race in the world are among the most prominent attractions of the Matanuska-Susitna (Mat-Su) Valley. The valley, lying an hour north of Anchorage by road, draws its name from its two largest rivers, the Matanuska and the Susitna, and is bisected by the Parks and Glenn highways. Major cities are Wasilla on the Parks Highway and Palmer on the Glenn Highway. To the east, the Glenn Highway connects to the Richardson Highway by way of several high mountain passes sandwiched between the Chugach Mountains to the south and the Talkeetnas to the north. At Mile 103 of the Glenn Highway, the massive Matanuska Glacier comes almost to the road.
