Here's an excerpt from Buchwald: "Several fragments had hit the trees of the dense taiga forest and had either broken them or damaged them. A 13.6 kg specimen was thus found firmly embedded in a partly split, 70 cm thick cedar tree."
and, on page 1126: Date of fall: Feb 12, 1947 Time: 10.38 a.m. (local time) Direction: N => S (10-15° east of north) Initial inclination: 41° The initial declination had increased to 60-70° at the time of impact (zenith angle about 49°). Apparent diameter of the bolide: 600m (with its luminous envelope). Length of smoke trail: 33 ± 9 km Dust trail observed for several hours. Brightness of bolide: exceeded that of the sun (about - 26) Point of complete breakup: 4 - 6 km (Hemmungspunkt) Initial velocity: 14.5 km/s Geocentric velocity: 9.2 km/s Heliocentric velocity: 37 km/s Preatmospheric mass: 1000 t Radius of light and sound phenomena: 300 - 400 km Largest fragment: 1.745 kg Specimens collected: 8.500 Total weight: > 23 tons It is estimated that a total of 70 tons fell, including dust. Impact holes: 122 (¢ 0.5 - 26 m / 1 - 12 m) Scatter ellipse: 1.6 km^2 ( N => S = 2.1 km /E => W = 1.0 km ) A smaller ellipse of 0.75 x 0.30 km was found to exist. Final velocities: 0.1 - 1 km/s Reference: BUCHWALD V.F.
