The year is 2000. Bruce's bike Banana Thunder looks west toward the Stucki Spring area from the viewpoint above Green Valley (top of the Huntsman World Senior Games hillclimb race course). The terrain you'll ride is rolling desert.
Stucki Springs Trail
via Bearclaw, Santa Clara, or Bloomington

The Stucki Springs Trail lies within the Bearclaw Poppy preserve southwest of St. George. The trail itself is about 10 miles long. While it lies in barren desert, it's a popular and well-traveled trail. The trail is intermediate technical but suitable for experienced conditioned beginners -- as long as you don't take the "Classic Stucki" plunge from the Race Course (see the options below).

There are many different riding options. You'll need to ride other trails to reach Stucki, so the typical ride will be 13 to 20 miles. I've tried to hold the options on this web page to 12-14 miles, within the range of the typical rider. Take more if you want to by adding other connecting trails.
You can reach the Stucki Springs trail from Green Valley in four different ways. You can arrive from Bloomington via two different trails. You can even get there from the Santa Clara River Preserve Barrel Roll trailhead. I'll cover the various options. Where you start from will determine your ride. Take your pick.

Typical trail on the southern side of the loop. We're looking north toward the Pine Valley Mountains as the trail zips and dips. March 2019.
The Stucki Springs trail is hard-packed desert clay. At the far north end, it's orange and red dirt. This part dries pretty quickly after storms. The southern 2/3 of the trail is white clay. Never ride this section when it's wet.
There are endless little dips. In some areas, it functions like a pump track. Especially on the section from the Cottonwood Wash overlook to Bearclaw , it's high-speed blazing fun.

For the clockwise ride, you'll be generally climbing from Bearclaw to the Cottonwood Wash Overlook at the ride's southwest corner. There are a lot of views as you ride westbound along the edge of Cottonwood Wash.
The mid-point of the trail is the Cottonwood Wash overlook. North of this spot, the trail generally follows the edge of the preserve. It continues northeast past Stucki Spring. At the north end, you can step over a gate to continue north on the dirt Stucki Spring Road to the Rim Rock or Barrel Roll trail systems.

Looking north toward the red cliffs near Snow Canyon. We're on the return trip back to Bearclaw. This is a high-speed section with a lot of dips and turns.
East from the Cottonwood Wash overlook, the trail snakes along the edge of the wash, then drops into badlands as it approaches Bloomington Hill. After meeting the Bloomington Microloop , it turns to Clavicle Hill and ends there on the Bearclaw Poppy trail.
You're riding on shale deposits of the Chinle and Moenkopi Formation, rich in fine volcanic ash. This formation dates to the Triassic Period, around 220 million years ago, just before the age of the dinosaurs. The mesas are formed by harder layers of mudstone that resist erosion, or by volcanic caps from lava flows. To the north, the Pine Valley Mountains are formed from an extinct giant volcano.

From the Bloomington trailhead for the Bearclaw Poppy trail , you can take the Bloomington Microloop to the southern end of the Stucki Springs trail. It's about 2.5 miles to the junction. Once you reach the Stucki Springs trail, you can veer west to go clockwise on Stucki, continue northwest on the Snakepit Trail to reach the far side of Stucki, or turn north on Bearclaw Poppy and veer to the left on one of the connectors to the Stucki Cutoff trail.
Bloomington: Bearclaw Poppy to Stucki out-and-back

A ride to the Cottonwood Wash overlook. 13-mile out-and-back. Head west on Stucki Springs to the viewpoint overlooking Cottonwood Wash (where the trail turns 90 degrees), then double back. From Bloomington, take the Bloomington Trail westbound (Bearclaw is one-way eastbound here). The trail twists and dips on hard-pack white clay as you head northwest under the slopes of Bloomington Hill. Never ride this trail when it's wet -- the clay is easily rutted.

South of Clavicle Hill, fork left for the Stucki Springs trail. Follow Stucki to the ride's highest point at Cottonwood Wash. You'll know you're there when you reach a fence where the trail turns 90 degrees right (to the north). Now backtrack the way you came. (Alternate: ride north on Stucki to the Snakepit trail, and use it as your return!)

Bloomington: Westbound Bloomington Microloop to Snakepit, Stucki to Bearclaw (Snakepit Figure 8)

Shortly after starting out on Bearclaw, fork left on the narrower Bloomington Trail. This trail is a little more difficult than Bearclaw, but not as scenic. It will drop into a wash for much of the trip. It parallels Bearclaw as it heads northwest. Go outbound on the Bloomington Microloop . Keep straight onto Stucki. Fork right into the wash and take Snakepit to the far side of Stucki. Fork left and circle around on Stucki. As you hit the 4-way, fork left to Clavicle Hill, then turn right on Bearclaw for the return.

Santa Clara: Stucki Springs Road to Stucki

From the Preserve parking lot at the Barrel Roll trailhead, backtrack to the Stucki Springs road (or continue south and cross Cove Wash then veer left to join the road later). After the road dips through the wash and climbs over a hill, you'll spot the Stucki Springs trail to your left at a gate in the fence. Continue south on the trail.

When starting from Santa Clara, most riders will do one of two possible loops. Follow Stucki past the viewpoint. To loop back, you fork onto Snakepit just before Stucki ends near Clavicle Hill. Or you can continue north from the end of Stucki to reach a connector to the Stucki Cutoff trail. (The Stucki Cutoff joins Bearclaw Poppy to the classic route from Green Valley. You'll rejoin Stucki right at Stucki Spring.)
Weve just crossed the fence and are heading southwest on Stucki Spring.

Rides from Green Valley Trailheads

Dominic finds some rock on the way to Stucki.
Green Valley: Classic Stucki Springs via Raceway

This loop is 19 miles, strenuous aerobic, intermediate technical with a rare smattering of advanced technical. Start in the valley downhill from the official Bearclaw Poppy Trailhead (and north of the Zen trailhead). Cross the little wash and find the downhill section of the Green Valley race loop . Go up the downhill singletrack. Near the top, turn right at the fork, following the race loop backwards.  Dominic cranks to clear the rocks while heading "up the down staircase" on the Green Valley race course. Photo 2000.

When you reach the road in the saddle, head for the little dip on the edge of the cliffs. Lift your bike over the fence and find the steep doubletrack heading downhill. Hang on -- it's going to be a plunge. Follow the marked trail almost to the fence and the spring itself. Turn left (southwest) on the main Stucki Springs trail.From the top of the mesa, this is the view back towards Green Valley. The trail can barely be seen heading across the valley below -- that's where you're headed if you ride the classic loop via Green Valley. February 19, 2000.

Heading west after dropping the big plunge from the GV raceway. The classic route is still well-marked with carsonite posts, even though the fence at the mesa top scares away the out-of-towners.
Most riders who take this route will ride counterclockwise to Clavicle Hill, then head north on Bearclaw Poppy. When you reach the step-over gate at the north end of Bearclaw, cross the road to the Barrel Trail Keep generally to the right as it drops you back to the race loop near the bottom of the hill.

North Bearclaw trailhead options

From the Bearclaw Poppy Trail parking area, head uphill to the step-over gate then ride the trail south. Popular options are:
(1) turning off Bearclaw onto the Stucki Cutoff trail, riding Stucki counterclockwise and returning via Bearclaw,
(2) continuing past Clavicle Hill to Stucki, then forking onto Snakepit and turning left on Stucki for a little loop and a return via Bearclaw, 
(3) out-and-back on Bearclaw plus the southern limb of Stucki to the overlook above Cottonwood Wash.

Bearclaw to Stucki via Cutoff 

After dropping the Three Fingers of Death, head south in the Wash on Bearclaw. Just after the trail pulls out of the wash, watch for a trail on your right. (There will be three more trails over the next half-mile, some of which are harder to spot. They all join into the same northwest-bound path.) This trail takes you to the classic route just below the bluff. Fork left. As you approach the fence, fork left and ride Stucki to Clavicle Hill. Backtrack on Bearclaw.

Green Valley to Cove Wash to Stucki

Head north on the doubletrack as though you're starting the Desert Rampage race. Follow the race course . When you hit the last doubletrack before Keyhole Wash, turn right. Follow it north until it drops down into a wash. Follow the wash all the way to the Stucki Springs Road. 

If there's water in the wash, you may want to fork to the right on doubletrack that parallels the wash.

When you reach Stucki Springs Road, turn left and follow the road. Keep left at the road fork (right takes you to the Rim Rock trails). After dropping down a hill, you'll find the singletrack across the fence on your left.

Getting there, Green Valley:
Take the Bluff Street I-15 exit in St. George and turn west. Immediately turn south (left). Go over the hill and turn right on Dixie Drive. Keep straight past the golf course and some businesses. Turn left at the sign for Green Valley Spa. (If you reach a "Green Valley Market" with gas pumps, you just passed it. Turn around and backtrack to the second road on your right.) Drive past the spa and park at the end of the road. From the top of the mesa, ride down across the wash. Keep left until you're through the fence, then turn right as the Green Valley trail turns left up the hill. Find the singletrack on the left about 100 yards up, just before the doubletrack drops into a rock wash.
Santa Clara Trailhead:  In St. George, head north on Bluff Street and turn left on Sunset Blvd. Drive 3 miles west on Sunset through Santa Clara. As you're reaching the end of Santa Clara, look for a road crossing the river on your left. It's about 200 feet before the Jacob Hamblin Home (which will be on your right if you pass the turn). Turn and cross the river and follow the road as it turns right. About 0.4 miles from Hwy 191, turn left onto the dirt Stucki Springs road as it climbs steeply south. At mile 0.7, turn right at the sign "Santa Clara Preserve" or "Cove Wash Trailhead." Pass the water tank, and at mile 1.3, turn right again through the fence. This road will veer left to a log-fence parking area at mile 1.5, N37 07.253 W113 40.508.
Bloomington Trailhead:  Go to the west end of Navajo Drive in Bloomington. Go across the cattle guard. See the low rail on the fence 100 feet to your right? That's the trailhead. N 37° 03.116'  W 113° 37.362'. Start out on Bearclaw Poppy, and fork left on the mini-loop about 1/3 mile later.
