UN 13,015 (formerly UN 13,020 interpolated) near Maroon Lake and Willow Pass has been determined to be no longer a ranked summit per Lidar evaluation, which gives it 292 ft. of prominence. This has reduced the total number of ranked 13ers from 584 to 583. We will be adjusting our list in the near future.
From I-70, west of Idaho Springs, take exit 238 for the Fall River Road/CR 275. This paved county road 275 ends in the vicinity of a mountain village called "Alice," mostly a collection of summer cabins, etc. This is the same road that leads up to the well-known St. Mary's Lake and Glacier. The road follows the Fall River in a generally NW direction. After 6.6 miles from the I-70/CR275 intersection, the road makes a second, abrupt switchback to leave the Fall River drainage and climb up to St. Mary's Lake and Alice. Continue north into Alice and turn left onto Alice Road at 8.4 miles. This will take you back west and SW for a short distance. Turn right onto Stewart Road. This road becomes FR 701.1. This will take you to Loch Lomond. There is a brown sign posted at this intersection with mileages. There is a lower and upper gate on this road that are seasonally locked. Access all the way to the Loch according to the Arapaho NF site is generally closed from mid-October to mid- July.
Note: If planning on visiting St. Mary's Glacier, a few tenths of a mile up from the turnoff for Alice Road, there are a couple of designated parking areas for hikers. These parking lots require a $5.00 fee to use from a self-service ticket/permit station. Be prepared to pay.
According to one site that rates 4WD roads, FR 701.1 is "suitable for stock, high-clearance 4WD sport utility vehicles. The road is still currently being described as very rough and rocky but easy to handle. Our combined memories recall that the drive back to the Loch was slow enough to make you reconsider if the drive was worth the effort versus hiking by another route. We would say the main advantage of this route is the visit to the upper lakes above the Loch. The collection of multiple lakes, waterfalls and cascading streams makes this area a beautiful respite to visit not far from the busy city.
On the way back to Loch Lomond on Steuart Road you can find some dispersed, primitive campsites. Just be sure you've driven far enough back to be away from any private property concerns.
