THRESHOLD COMPLEX EXPLORATION LOG
Designation / Log ID: 63-H60
Apparent Date/Time: 08 October 2026 / 09:22 (local) — secondary stamp reads 02:17 11 November 1968
Entry Method: Service door marked “M-73 MORTUARY DRAWER GALLERY – STAFF”. Exterior clear aperture measures 0.88 m × 2.03 m. Interior aperture measures 1.06 m × 1.91 m on entry and 0.74 m × 2.21 m on exit.
Environmental Baseline
Lighting: fluorescent troffers, color temperature measured at 3900 K. Intensity constant at 142 lux.
Ambient temperature: 4.6 °C. Humidity: 71 %.
Background sound: drawer latch at 0.4 Hz. Baseline reading 28 dB.
Air movement: none detected. Barometric pressure 1016.1 hPa on entry; 1004.8 hPa after 5.2 m of travel.
Spatial Observations
Gallery estimated 18 m long by 6.1 m wide by 2.8 m high. Laser measurement returns 27.4 m long by 4.3 m wide by 3.6 m high.
Floor: sealed concrete with inlaid trolley guide. Guide width measures 40 mm. Surface remains uniform under repeated contact.
Walls: stainless panel with eight drawer banks and one tag rail. Drawer face height measures 380 mm. Surface remains uniform under repeated contact.
Ceiling: insulated panel with two troffers per bay. Fixture count remains eight after five visual inventories.
Repeating motif: every 1.4 m a drawer bank occupies the wall. Bank depth measures 2100 mm. Finish is identical across all units.
Anomalies
Visual inventory of drawer faces returns 48. Physical inventory returns 48. Measured occupied-drawer count equals 0 while calculated residual tag count across the same banks equals 31.
Floor remains level under spirit level. Measured residual frost on the drawer lips slopes 0.8° toward the outbound wall. Slope reverses after 7 minutes of observation without change in physical orientation.
Posted capacity plaque reads 8 BANKS / 0 OCCUPANTS. Measured combined compressor current equals 0.0 A. Bank lamps remain green.
Sound of residual latch impact arrives 2.4 seconds after the corresponding drawer motion is detected. Delay increases by 0.19 s for every additional 1.0 m of distance from the entry door.
Humidity at mid-gallery remains 71 % while residual frost forms on the tag-rail edge after 9 minutes of observation. Frost disperses without measurable change in humidity.
Magnetic field strength measures 0.4 gauss at floor level and 1.7 gauss at 1.5 m height. Field direction reverses after 8 minutes without change in gallery state.
Tag stock on the open rail decreases by 6 over 14 minutes while measured rail-lock current remains 0.0 A.
Surface of residual frost on the drawer lip exhibits surface tension hold of 1.1 cm against vertical steel. Hold collapses after 41 seconds without measurable change in frost volume.
Trolley guide migrates 5 mm toward the inbound wall over 6 minutes. Guide returns to original alignment without measurable change in floor temperature.
Drawer face height measures 380 mm on first inventory and 310 mm on second inventory of the same face. Face returns to 380 mm on third inventory without change in wall position.
Bank depth measures 2100 mm on first inventory and 1640 mm on second inventory of the same bank. Bank returns to 2100 mm on third inventory without change in wall alignment.
Recorded latch interval equals 2.50 s on the first 10 cycles and 3.80 s on the subsequent 10 cycles. Interval returns to 2.50 s without change in latch state.
Drawer interior temperature measures 4.6 °C. Residual heat print on the same steel measures 19.4 °C after 8 minutes without measurable change in ambient temperature.
Latch switch at bank 4 registers 0.0 V across the interlock. Drawer motion is present. Motion ceases after 19 seconds without change in switch state.
Entity Notes
None observed.
Exit / Continuity Status
Exit achieved through the same service door after 26 minutes of observation. Exterior aperture on exit measures 0.74 m × 2.21 m. Residual frost marks on gloves dissipate within 11 minutes of exit. Magnetic field returns to baseline 0.4 gauss within 13 minutes. No further residual effects recorded.
