Summit County Area Info

The county is in the high rockies located just west of the Continental Divide. The lowest point of elevation is at Green Mountain Reservoir in the northern end of the county at 7,947 feet. The highest point is on top of the Continental Divide where Gray’s Peak tops out at 14,270 feet.

Lake Dillon

Lake Dillon is a reservoir holding Denver’s drinking water. Frisco and Dillon have marinas and are lakeside. Silverthorne is just downstream from the lake. Keystone, Breckenridge and Copper Mountain are just up the road. The reservoir was built in the 1960s. Before they could build it, the town of Dillon had to move out of the valley. Some buildings, like the Old Dillon Inn (ODI) and The Mint were moved to higher ground. You can still grill a steak at The Mint today. However, most of the town remained and, from what I am told, still sits at the bottom of the reservoir. The Upper Blue River from Breckenridge, the Snake River from Keystone and Ten Mile Creek from Frisco all flow into Lake Dillon. The Lower Blue River that runs through Silverthorne flows out of the lake.

The Mountains of Summit County

Gray’s Peak is a 14er. Meaning the peak of the mountain is over 14,000 feet high. There are three 14ers in Summit County. Quandary Mountain is the only 14er completely in Summit County. It’s elevation is 14,265 feet. The third 14er is Torrey’s Peak. It is connected to Gray’s Peak and also sits on the Continental Divide. The Continental Divide is the county line so half of Gray’s and Torrey’s are actually in the neighboring, Clear Creek, county.

Even though there are only three 14ers in the county, there are still a lot of high mountain peaks you can summit. The Gore Range is a gorgeous mountain range and includes Buffalo Mountain. The Ten Mile Range is the mountain range that run from Peak One above the town of Frisco to Peaks 6, 7, 8, 9 and 10 that make up the Breckenridge Ski Area.

The Eisenhower Tunnel

The Eisenhower Tunnel made access to Summit County and the rest of the western slope much easier. It is the highest vehicular tunnel in the world. It took several years to complete construction of the 1.693 mile long tunnel. Construction for the Eisenhower bore, which is currently the westbound lanes, took five years. It was completed in 1973. The Johnson bore was complete in 1979.

The Weather

Summit County’s high mountain peaks get a lot of snow. Most resorts tout 300-400″ of snowfall per season. That’s more than 25 feet. It can snow any time of year. Most often our snowfall starts in October and continues through April. Temperatures can fall below zero but when they do, it is generally a cold snap that is short lived. Most often we have temperatures in the 20s and 30s. January is the coldest month. Humidity is very low and we have a lot of sunny days in the winter. That makes it feel warmer than the thermometer says.

Summertime temperatures are generally in the 70s. On occasion it can get into the 80s. The low humidity keeps it comfortable. Our summer rain is usually moderate showers. We rarely see big downpours. We can get a rainy day here and there but most often we see nice mornings that give way to afternoon showers. They clear out and we have cool evenings. The temperatures drop overnight making for great sleeping weather with the window open a bit. Air conditioning is non-existent here, except in commercial establishments.

Partial Ownership

Properties are also available as partial ownerships, meaning you can buy a portion of a property. You can buy one quarter or one tenth of a property for example. They are similar to a timeshare but when you buy a timeshare, you are buying time. When you buy a partial ownership, you are buying deeded interest in the property. Generally a partial ownership will have rules that govern the property and each owner will be responsible for their portion of expenses. It can be a way to enjoy a vacation home at a portion of the cost. There is a lot to know about partial ownership. You can keep reading to get additional information about partial ownership properties.
