May 2015 – Black Hawk Canyon
Many times while hiking, I find myself quizzically inspecting an unidentified geological formation, examining an interesting rock, or stumped on how a white line of quartz got in the middle of the earth, marked there like nature’s 50 yard line. I wanted to learn more about the geology I’ve been seeing on my hikes and so, after some digging, I was put in touch with local hiker Lee Stockman of the Grant County Rolling Stones Gem and Mineral Society. He has been interested in geology his entire life and told me that he looks at rocks with a chemists’ eye since that’s what he did for a living – a chemist at the water treatment department in Antioch, Ca. To emphasize his love of Geology, on the car ride to the trailhead, he pulls out a rock sample and shows his passengers. It is smooth and grey and has glittering silver specks throughout it. It turns out to be a sample of Native Silver from the Alhambra Mine which is very close to where we will be hiking today. I just got my first, but not last Geology lesson of the day. I wish I had this man for a science teacher all those years ago!
Lee hikes every week with a group of like-minded people and he offered to let me join them. Throughout the morning, Lee shares various interesting tidbits. When the group inspects white lines through a huge granite wall, he explains. “The granite cracked and super-heated water carrying minerals rose through the cracks. The water cooled and left the minerals in the cracks forming the lines we see today”.
On the trail, various rock specimens were passed around the group and inspected. “That’s a unakite – you can tell by the green stripes and the pink feldspar throughout it.”
At one point, a few hikers surround a green plant in the middle of the arroyo. They’re not seen often around here. The group calls out to Richard Felger, the resident botanist. “That’s a Desert Broom, Baccharis sarothroides.”
Describe one of your favorite hikes that you’d like to share with the readers:
Name: Black Hawk Canyon Loop
Directions: From the intersection of Highways 180 and 90, take Highway 180 West 12.9 miles to Saddlerock Canyon Road (on south side of highway). This road is close to Mile Marker 100 and is right after Mangus Valley Road. Make a left on Saddlerock Canyon Rd. Track your mileage from the highway turnoff. Travel on dirt road for 1.3 miles and go over the cattle guard. At the 1.4 mile mark (mm), the dirt road divides. Stay to the left. At the 1.5 mile mark there will be another fork. Stay left. At the 4.3 mm, stay straight. There are several side roads; when in doubt, stay on the main road. At the 5.2 mm, you will come to a closed gate. Go through the gate, closing it behind you, and continue on. The road peters out around the 6.4 mile mark. The hike starts here.
Hike Description: Before starting the hike, look to the left and see a washed out dirt road going up a hill. If you’re positioned correctly, you’ll see some old mining equipment. This is where you will come out from this loop trail. Now start your hike by walking straight up the arroyo and into Black Hawk Canyon. Soon you leave the sandy creek bottom and begin to climb across the water worn granite. This granite intrusion (dated at 1.445 Billion Years old) raised the Burro Mountains. There is usually water here even during the dry season so look for paw prints of the wildlife who inhabit this part of the Burro Mountains. At the .78 mm, there is a side road that leads to the old Alhambra Mine. Make a note to go back and check it out sometime. Continue straight until you reach the .93 mm. To the left is FR 130. This is the road that loops you back to the car. But first, walk straight ahead on FR 4242Q for a while and enjoy a pink granite canyon. When you’re ready, come back to the road and take it up a hill. When you reach a ‘T’ in the trail, turn left. Towards the end of the hike you’ll come to your last fork. Make a hard left and head down hill past the Black Hawk mine.
Notes: There will be some mild rock climbing and muddy spots along the first portion of the hike. At a few spots you will enjoy views of Bullard Peak. Expect to encounter cattle. They like to have their pictures taken, so ask them to smile. Several hikers mentioned previous kudamundi sightings in this area.
History lesson: The mining town of Black Hawk appeared in the 1880’s when silver was discovered in the area. The discovery of the Black Hawk Mine, and several others in the area, saw the beginning of the town. In the summer of 1883 the town had approximately 30 men employed in mining. By the end of the same year, there was close to 125, and the town was large enough to include a post office. In the late 1880’s production declined and the town was vacated. Today, hardly any evidence of the town exists. By the end, the Black Hawk Mine had produced one million worth of silver.
What can a reader do to learn more about the minerals in our area? Lee encourages readers to attend a meeting of the Grant County Rolling Stones Gem and Mineral Society. The meetings are on the 2nd Thursday of the month at the Silver City Senior Citizens Center (204 West Victoria at south end of town off of NM 90). A pot luck precedes the meeting at 6:00 pm. The meeting begins at 6:45 pm and is followed by an educational program.
