Crop Circles

Crop Circles is a series of loop trails just north of the Dry Canyon Bonneville Shoreline Trailhead on the hillside above Lindon. These "social trails" have been adopted by the U.S. Forest Service as official public trails. There are no trail markers or signs at this time (spring 2022), as official trail designation signs are still awaiting funding. 

The trails are most easily found by heading north on the Bonneville Shoreline Trail (BST) from the Lindon (Dry Canyon) Trailhead. There are lots of old abandoned roads, game trails, and old hiking routes here, so you should have a means of knowing where you are. A GPS navigation app such as Trailforks is strongly recommended. The area has been closed to motor vehicles for only a few years, so you'll cross the remains of old jeep paths.

View uphill from the trailhead. Resist the temptation to ride up Dry Canyon. It can be done, but it's too steep to be fun, and it becomes unrideable after about two miles.

There are four loops stacked on the hillside. Below the BST, there's thewhich forms a loop with Canberra, Sunshine, and a piece of the BST. North and uphill is, forming a loop with the BST at the bottom. Above the main Crop Circles loop via a short connector is the(designated forest trail #316). And at the top of the Middle Crop Circle is a short connector uphill to the#317.

Starting out on the Bonneville Shoreline Trail from the Dry Canyon trailhead. The south end of the main Crop Circle is 0.4 miles (and a bit of uphill) away.
From the BST/Dry Canyon parking lot, backtrack to the north end and find the trail near the metal gate. Stay on the BST (as a few alternate paths fork away) for 0.4 miles. As the trail veers to eastbound (directly towards the mountain) for the first time, spot a trail forking 90 degrees right (south) just before the BST turns back northbound. That's the south end of Crop Circles.
The main Crop Circles loop is 1.9 miles around (1.5 miles of the Crop Circles trail and 0.4 miles of the BST at the bottom). The climbing rate is generally easy and the trail surface is non-technnical.

Climbing through larger trees and cooler temperatures on the south side of the main Crop Circle.
This trail will climb up the mountain through some gentle switchbacks. At mile 1.0 from the BST (1.4 from the Dry Canyon trailhead) you'll reach the "stem" that connects uphill to the Middle Crop Circle. The smaller trail breaking downhill left is the continuation of the main Crop Circle as it drops 0.5 miles down to the BST (see map). Most riders will plan to take this trail on their way down.
If you complete this lower circle without going higher on the mountain, it will be 0.4 miles on the BST back to where you entered the circle and another 0.4 miles back to the trailhead.
Note that the Sumac Hollow trail will join the northern limb of the Main Crop Circle for a short distance. In 2022, the trail signs that would help you sort this out are still waiting.

Middle Crop Circle

At mile 1.0 of the Crop Circles trail (riding counterclockwise, northbound), a connector goes uphill to the Middle Crop Circle. The connector is 0.1 miles long, then the uphill route splits into the Middle Crop Circle. You can go either direction, so take either one uphill, then ride the other one downhill. (Or ride around in a circle now. It's all good.)
Stay on the narrower singletrack as it joins then leaves a wider route. (Here's where your navigation app helps!) The wide trail is Sumac Hollow, see below.
The Middle Crop Circle is 0.7 miles around. At the circle's highest point, a connector goes uphill to the Upper Crop Circle. The northern limb of Upper Crop Circle is 0.3 miles, while the southern limb is 0.4 miles. Most riders will climb via the southern limb.

As noted above, one section of the southern limb of the Middle Crop Circle is shared with the Sumac Hollow trail. When climbing, the trail will make a hard right turn to join a bigger trail. That's Sumac Hollow. After 100 yards of climbing, veer to the left to leave the combined trail.
Upper Crop Circle
At the top of the Middle Crop Circle, another short connector (a bit over 0.1 miles) takes you up to the Upper Crop Circle. At the fork, the easiest navigation will be to keep left and ride the loop clockwise.

Near the end of the clockwise loop (or shortly after starting Upper Crop Circle when going counterclockwise) you'll find yourself at the fork to the connector to Curley Springs and upper Sumac Hollow. This trail heads straight south traversing the hill. It will dump onto the rough steep Sumac Hollow trail after about 1/10th mile.
As you complete the loop, head back on the stem to the Middle Crop Circle, then on to the main Crop Circle. On the way down, drop to the right into the oak brush for the north side this loop. At the BST, fork left and head south.

Lower Crop Circle

There's also a loop below the BST. This loop actually consists of three named trails. You'll run across the trail fork to this lower loop in a grass meadow about 0.1 mile after passing the fork where you originally left the BST for Crop Circles (0.5 miles from the Dry Creek trailhead).
Turn hard right and descend, first straight, then through a series of tight turns. As you near the bottom, turn left on a horizontal trail to head southeast. Cross a fall-line trail a few feet later. You're now on Canberra trail #311, sometimes called the lower BST.

Keep straight at a connector down to the homes on your right, then just as you see a corner of chain link fence around the homes, turn left uphill again on singletrack. This is the Sunshine trail. and it will climb back to the BST. It joins the BST about 100 yards west of the Dry Canyon trailhead. Turn left for more riding; right to descend to the trailhead.
Sumac Hollow trail

The Sumac Hollow #310 trail has been designated as an official route by the Forest Service. At this time (2022), it's cobbled together from several bits of trail and you'll almost certainly take a wrong-way trail fork on your way down. Hopefully, future signs -- and closure of the many unofficial trails -- will make the navigation more obvious. But this will not be your favorite trail in the area.
The main purpose for Sumac Hollow is to provide a wide and straight path for horses and hiking groups to get up and down the mountain. So while the Sumac Hollow trail shares some mellower pieces of the main and middle Crop Circles, the rest of it is steep and loose. It's 1.2 miles long with 750 feet of elevation change. Some bikers will enjoy the blistering descent. It's not a pleasant climb.

Looking down Sumac Hollow shortly after leaving the Curley Springs trail. Most riders will never make it up this far. They'll take the trail down from the Upper Crop Circle.
At the top, the trail starts as the old access road from the ridge where the Curley Springs trail turns north. Just after mile 0.1, there's a singletrack on your right that connects over to the upper Crop Circle loop. At mile 0.25, the trail joins the middle Crop Circle loop for around 100 yards. Keep straight here. At mile 0.4, you'll cross the downhill side of the middle Crop Circle.
At mile 0.5 comes the first critical fork. The trail drops into what appears to be an S turn with the wide path dropping steep downhill to your right. That's not the trail! Instead, veer left on a less-traveled (and fairly flat) path. Now the trail will join and leave the Main Crop Circle. Just keep straight southbound through this area.

Coming into the turn where I took the "obvious" path and wound up on the BST. Had to climb all the way back up to figure it out.

The next critical fork is at mile 0.8 and this one's a doozy. When the trail hits the fork between the BST and the south end of the main Crop Circle, stay a bit left. After crossing the Crop Circle trail, take the smaller trail to the left. The more-obvious trail straight and to the right is an unofficial route that drops to the BST.
Once you get through this jumble, it's a straight shot down to the parking lot.

Other area trails
Curley Springs:
  The Curley Springs trail runs from the Dry Canyon Trail to Battle Creek Canyon. It traverses the mountain above Crop Circles and can be reached via a rough old doubletrack from the southeast corner of the Upper Crop Circle. Curley Springs is rough, eroded, and postholed by horses. It connects at the north end to Battle Creek, a very rough steep trail, littered with boulders, that descends to the Battle Creek BST trailhead (or via push-a-bike uphill to the Timpanogos Perimeter). On the south, Curley Springs connects to Dry Canyon, descending down to the Lindon BST trailhead. Uphill, Dry Canyon connects via steep trenched non-rideable trail to the ridge above Baldy on the GWT. If you're thinking about a loop with a short bit of Dry Canyon uphill, Curley Springs northbound, lower Battle Creek downhill, then BST southbound back to Lindon, it can be done. But it's nasty. Both Battle Creek and Dry Canyon often have a 20% slope; 1000 vertical per mile.  You'll push your bike a bit. The unpleasantness factor is just too high for me to recommend it.

Curley Springs mini-loop
There's a little loop ride on the south end of Curley Springs. I recommend doing it clockwise. Starting on the connector to between the upper Crop Circles and the Sumac Hollow trail, you'll climb the last (steepest) bit of Sumac Hollow up to the Curley Springs trail #51. A clockwise ride includes the Upper Curley Springs trail #318, a fairly easy traverse of 1/2 mile, then a short steep piece of Dry Canyon #49 best done downhill, then a climb up lower Curley Springs (taking the easier new alternate trails) for 0.6 miles to complete the 1.4-mile loop. This can be a fun addition to a Crop Circles ride if you've got the leg for it.

NOTE: Trails on this map shown in light blue with outlines are routes that currently are seeing substantial use, but are (to my best understanding) scheduled for re-wilding after signage for the official trails is in place.
Getting there, Dry Canyon Trailhead:
Turn east off State Street (Highway 89) at 200 South in Lindon, which also happens to be 2000 North for Orem. Keep straight as you approach the mountains. When the road begins to turn right (south), turn left onto Dry Canyon Drive heading northeast. Now keep straight uphill until the road turns into the trailhead. The parking area is at N 40° 20.52'  W 111° 40.62'.

Bathroom at trailhead.
No camping nearby.
