Revised July 10, 2000

Hiked 1989, 1989, 2000

Sometimes it takes more than one try to get it right, as Aimee and Mike learned in what they thought would be a relatively easy hike of the Union Spring Trail. The original plan was to park at the Government Peak trailhead on M-107, hike in two miles to the Union Spring Trail, then hike either two miles to the spring, or four miles to South Boundary Road, before doubling back. The option of the shorter hike would require them to complete the segment of the trail from South Boundary Road to the spring on a later hike.

The first attempt according to this plan took place in mid-May, 1989. To illustrate typical western U.P. weather, there were still patches of snow on the ground in shaded areas along the Government Peak Trail. Accessing the Union Spring Trail required us to cross the Upper Carp River, which is difficult to do without getting your feet wet since there's no bridge and no really effective crossing aids like logs or stepping stones.

We were doing fine over the first 1 1/2 miles along the trail, until a point about 1/2 mile before the spring. The trail makes an abrupt, close to 180 degree, change in direction at this point. Instead of following this to the right, we made a much less sharp turn to the left, which unknowingly put us on some unnamed cross-country ski trail. We later noticed the blue blazes (this was at a time when the hiking trails used red diamonds -- they now use the same blue blazes) but Mike also realized our direction was going to shortcut back to the Government Peak Trail, which it did in the vicinity of the Overlook Trail junction.

Our second attempt was made about a month and a half later, on July 3, 1989. This time we accessed the Union Spring Trail from South Boundary Road, about two miles south of M-107. Hiking to the west, we crossed the Union River after about 3/4 mile. At that time, the river cut across the trail at a shallow angle and it was relatively easy to ford. After another 3/4 mile, we came to the Union River Impoundment, formed by an earthen dam across the river. The trail passes over the top of the dam.

The major attraction of this trail, Union Spring, was reached another 1/2 mile past the impoundment. There is a wooden viewing platform where you can watch the bubbling action of Michigan's second largest natural spring, flowing at over 700 gallons per minute according to the park brochure. (The state's largest spring is located near Manistique in the south central U.P. and flows around 10,000 gallons per minute.)

We hiked beyond Union Spring as far as the point we'd reached before making the wrong turn on our May hike, then doubled back to the beginning. Since we'd only hiked five miles roundtrip, we decided to complete the one mile Union Mine Trail, located adjacent to the Union Spring trailhead, on the same trip.

We expected Union Mine to be a "wimpy" short nature trail for people who were unfamiliar with wilderness hiking. That's not the case. The only thing easy about it was the distance. It was not flat -- there were some moderately steep climbs and descents. There was some interesting scenery including old mines and waterfalls. This short trail would be a good brief introduction to what it takes to hike the Porkies for someone who hadn't been here before.

On June 26, 2000, Mike and Maria hiked the Union Spring Trail from South Boundary Road to Government Peak Trail, then followed Government Peak Trail two miles to the M-107 trailhead. Aimee dropped them off then picked them up to facilitate the six-mile, one-way hike.

Recent rains had made most of the trail muddy that day, but Maria was able to hike the first two miles past Union Impoundment to Union Spring on her own two feet. It was no longer necessary to ford the river apparently due to a slight trail rerouting including a bridge. We stopped at Union Spring for lunch, then Mike carried Maria in the backpack.

The signage at the confusing ski trail junction was substantially improved, with the trail indicated by a hiker graphic and labeled "Summer Trail" while the cross-country ski route was signed with a skier graphic and labeled "Winter Trail." Mike noted that it was actually possible to see the spring from the junction by looking straight ahead if you were hiking in the west to east direction. To be honest, I don't know how we missed it in 1989.

I don't remember how wet our feet got in 1989, but on this hike, it wasn't possible to cross the Upper Carp River to reach the Government Peak Trail without stepping off stones in a spot or two. Mike continued carrying Maria in the backpack along Government Peak Trail, as far as the Escarpment Trail junction, then he let her walk the remaining 1/4 mile to the M-107 trailhead where Aimee was waiting with the car.

One thing to remember: The stream crossing of the Upper Carp River at the junction of the Union Spring and Government Peak Trails is probably the only remaining difficult crossing in the park that doesn't have a bridge. I'm guessing there will never be a bridge here, since the crossing occurs in the vicinity of Trap Falls and a bridge would be likely to wash out. "Difficult" is a relative term -- the day Mike and Maria crossed, the deepest water was about three to six inches.

The famous Union Spring
Union Spring is the second largest natural spring in Michigan. The bubbling action of the spring is readily visible in the sand at the bottom with reflections of trees at the water surface. This photo was taken on July 3, 1989.

The previous photo was taken from a platform which extends into the water to facilitate viewing the spring.
Union River Impoundment
About a half mile downstream from the spring, the trail passes over a dam which forms the Union River Impoundment.
Maria at Union Impoundment
Maria poses at the impoundment on June 26, 2000. She had hiked the first 1-1/2 miles to this point on her own two feet and completed the remaining 1/2 mile to Union Spring before Dad began carrying her in the backpack.

Maria near Union Spring sign
Here's proof that Maria hiked two miles on her own two feet a few days before her 5th birthday. This broke her previous record of 1.8 miles on the Black Forest Trail in Pennsylvania in October, 1999.

She also read the "No Fishing" sign and looked for fish in the spring, but all we saw was one eel.
Crossing Upper Carp River
The junction of Union Spring and Government Peak Trails is divided by this stream crossing of the Upper Carp River.
Falls at Little Union Gorge
The Union Mine Trail passes a number of points of interest, including waterfalls on the Little Union River at Little Union Gorge, just east of South Boundary Road.
