On December 21, 2025, the winter solstice sunrise was observed and recorded aligning precisely through the gap formed by the two upright lithic slabs. The alignment had been anticipated from the gap geometry and horizon azimuth prior to the event. Two U.S. Forest Service archaeologists were present as witnesses. The precision of the alignment, where the sun rises centered in the gap at the moment of solstice, is consistent with intentional orientation of the monument.
Two tall monzogranite clasts stand upright on a tonalite bedrock platform at an elevated ridge position with an open eastern horizon. The upright monzogranites are medium- to coarse-grained and consist of biotite leucomonzogranite, leucogranodiorite, and syenogranite which are more resistant to weathering than any other granitoid. Small shim stones are positioned at the base of both uprights, behind the left clast and in front of the right, stabilizing their position in a manner inconsistent with natural emplacement. The gap between the two uprights frames the winter solstice sunrise precisely.
The monument does not stand in isolation. The surrounding landscape contains multiple associated features distributed across several hundred meters, collectively suggesting a multi-functional, repeatedly visited site over an extended time period. Features include fire-darkened boulder depressions to the north, tafoni erosion features in the surrounding area with possible anthropomorphic modification for cultural use, and mano handstones recovered approximately 800 meters to the south — indicating the broader complex extends well beyond the monument itself.
