Entry No. 28 — the Boulder file — filed under: sacred geometry
The StarHouse
Built between 1989 and 1990 by a small founding community dedicated to sacred geometry, the StarHouse is a wooden ceremonial hall whose axis aligns precisely with the North Star and the four cardinal directions — the structure is, in the founders' own words, "a star map." Its triangular form embodies the Pythagorean tetractys, a ten-point figure arranged in four rows, and its proportions encode solstices, equinoxes, and planetary positions. Surrounding the hall on 140 organically certified acres are nine outdoor sacred sites: a zodiac standing-stone circle with 1.5-billion-year-old Colorado stones, a seven-circuit labyrinth whose walls were built one stone per visitor, a human-scale dodecahedron, a "Power Tower" filled with paramagnetic stone, and a Council Grove of old-growth Ponderosa pines. All Seasons Chalice Church has stewarded the property since its incorporation in 1994.
The story
In 1989, visionary David Tresemer and a small circle of builders began assembling a timber hall at 7,000 feet in Sunshine Canyon with a ruler, a compass, and a set of cosmic coordinates. Completed in 1990 and stewarded since 1994 by the All Seasons Chalice Church, the StarHouse wasn't just built beneath the stars—it was built as a physical star map. Its primary axis points directly at Polaris, its orientation locks onto the four cardinal directions, and every angle of its wooden frame encodes the solstices, equinoxes, and planetary alignments.
The geometry extends far beyond the main hall's triangular frame, which reproduces the Pythagorean tetractys—a ten-point figure stacked in four rows. Step outside onto the 140 organically and biodynamically certified acres, and you'll find nine outdoor sacred sites tucked across the canyon bowl. There's a human-scale dodecahedron you can step inside, a Power Tower packed with paramagnetic stone designed to capture low-frequency cosmic waves, a seven-circuit labyrinth whose stone walls were laid one rock per visitor, and a zodiac standing-stone circle quarried from 1.5-billion-year-old Colorado stone.
What it's like
You can't just pull off Sunshine Canyon Drive whenever you feel like communing with the stars—drop-ins are strictly barred. To cross the threshold, you need to pre-register for a full moon ritual, seasonal solstice gathering, or designated member day. When you go, ignore your GPS if it tries routing you to Linden Drive (that road dead-ends at a locked gate). Look for the 3476 address marker 3.5 miles west of 4th and Mapleton, pull into the unpaved top lot, and wear shoes with real tread. The two-minute walk down the chip-wood path into the quiet canyon bowl strips away the city before you ever step through the timber doorway. Aim to arrive 30 minutes early so you can trace the stone labyrinth in peace before the ceremony begins.
The move: Attend a new moon or full moon ceremony together, then spend the hour before or after wandering the stone labyrinth and standing-stone zodiac circle at dusk. The short walk from the parking area down a chip-wood path into the canyon bowl sets the mood before you even step inside.
📍 Before you go The property is not open for drop-in visits. To walk the grounds you must either be registered for an event (arrive up to 30 minutes early) or attend a member day. Events run year-round — summer solstice and new/full moon ceremonies are the easiest entry points. Park at the top of the unpaved driveway and walk two minutes downhill; wear shoes with grip. Do not follow GPS to Linden Drive — it leads to a locked private gate.

Good to know
Can I visit the StarHouse grounds anytime for a quiet hike?
No. The property is private and closed to unscheduled drop-in visitors. You must be pre-registered for an event or attending an official member day to walk the grounds and access the sacred sites.
How do I get there without getting lost?
Drive exactly 3.5 miles west from 4th Street and Mapleton Avenue on Sunshine Canyon Drive. Do not follow GPS directions to Linden Drive, as it leads to a locked private gate. Park at the top unpaved driveway and walk downhill.
What is the best way for a newcomer to experience the space?
Pre-register for a public new moon or full moon ceremony, or a seasonal solstice/equinox event. These run year-round and provide guided access to both the ceremonial hall and the outdoor sites.
What should I wear or bring for an evening event?
Wear sturdy shoes with solid grip for the unpaved driveway and chip-wood path, and bring warm layers. Temperatures in Sunshine Canyon drop quickly at dusk at 7,000 feet elevation.
