Follow the dirt road south marked with the blue blazes of the Mattabasset “blue trail” for .1 mile to where it leaves the dirt road and heads west (right). Take care to follow the blue blazes as a number of woods roads and old trails cross the path. At the eastern base of a major north-south running ridge, the trail reaches Pyramid Rock, a large block of outcrop displaced from the ridge above by glacial forces 10,000 years ago. Here, just past the rock, the orange-blazed interior trail of Mica Ledges Preserve leads south (left). Continue steeply upward on the blue-blazed trail. Here hemlocks have been ravaged by the Wooly Adelgid. Many dead and dying trees attest to the debilitating and lethal effects of this insect invader. At the ridge top, the trail swings southward and, at times, breaks out into openings on the high granitic ledges that give the Preserve its name. Splendid views to the west of the valley below and the basaltic trap rock ridge beyond can be had from these heights.
About .5 mile from Pyramid Rock, in a sight saddle along the ridge, an orange-blazed trail leads to the east (left) and down to Whitney Pond. This is the east-west cross-over trail referred to later. On the Mattabasset, just beyond this juncture, a cairn of stones marks the spot where the towns of Durham, Madison and Guilford share a common boundary. A few yards south of the cairn, the trail descends sharply and crosses a small, beautiful stream, then ascends steeply once more to bare rock and dry oak forest. At times, understory of huckleberry and blueberry give way to dense mountain laurel. Eventually, the trail dips and then rises very steeply through another ravine. Such ravines accumulate organic matter and eroding rock from above and consequently provide better growth conditions than on the thin-soiled exposed ridges sites. Note how much larger and better formed the trees are in such places. Once again, the trail breaks out on west facing ledges and continues south (eventually it crosses over to Bluff Head – the southern end of the trap rock ridge to the west).
Turn east (left) onto a Land Trust trail, marked with orange blazed. The species of pine ground here, pitch pine, is found in such places where moisture is limited and where fires occasionally occur. Heat helps the cones to open and disperse their seeds. This orange-marked trail is the west end of the Maria Schmidt Memorial Trail. Follow it east a few hundred feet to where a loop of the trail branches right and eventually rejoins the main trail just a short distance ahead.
The loop trail descends into a protected valley strewn with boulders whose rounded edges attest to their glacial transport and deposit. Follow the trail into Town of Madison open space and then upward onto a flat outcrop where in 1998 a fire burned for several days. Dead trees and a heavy grass cover now bear witness to the event.
Continue back into Mica Ledges Preserve to where the loop rejoins the main trail and proceed north (right) and northeast through a forest with chestnut and red oaks now taller and of finer quality than on the ridge just traversed. As the trail descends into the sheltered, moist, northeast-facing valley, beech, red maple, and black and yellow birches become more abundant. The Maria Schmidt Memorial Trail ascends once more through laurel thickets on the ridge before ending at the east-west crossover trail that connects with the Mattabasset trail to the west (left), Whitney Pond to the east. A few yards to the east is the south end of the north-south running orange trail that leads back to Pyramid Rock (that portion of the trail is described below). To the west, 425 feet toward the Mattabasset, the crossover trail passes directly through the remains of an old charcoal mound revealed by a nearly circular area with darkened soil, charcoal fragments and very little vegetation. Just beyond, the trail crosses the bed of another intermittent stream and then gradually rises to join the Mattabasset trail near the western ledges. From the juncture of the Maria Schmidt trail and the crossover trail, hikers can return to the trailhead via the Mattabasset trail, by the north-south orange trail, or by continuing east to Whitney Pond and following the road system back north.
From Pyramid Rock go south, first along and through a great jumble of large rocks fallen from the ridge above, then, where the trail meets a logging road, turn sharply upslope to where a beautiful vernal pool with its backdrop of rocky outcrop and pitch pine presents and oriental and mystical appearance.
The blazed trail travels up and to the south and passes, near the eastern drop-off, a series of caves formed by the fractured rock tallus. Beyond, the high dry oak forest with laurel thickets speaks to the thinness of the soil and to the general low water availability on these rocky ridges. The trail continues upward, passes by another vernal pool and then, turning east (left), eventually emerges into an opening where great views can be had to the east of the ancient central Connecticut Highlands Geologic Province. Mount Pisgah can be seen to the northeast. Pitch pines, scrub oaks and dry understory of blueberry, huckleberry, etc. are characteristic of these open, storm-swept sites. Follow the trail southward and then down to the east. Through the trees, especially in the dormant season, good views can be had of Whitney Pond. Follow the trail down by Whitney Rocks to mid-slope and then south the where it joins the east-west trail crossing from Whitney Pond to the Mattabasset Trail to the west.
