Frank,

It came from the SSW (south south west) traveling to the NNE?

>From this trajectory I now strongly suspect that the Richardton meteorite of June 30th 1918 is indeed a member of the Beta Taurids. And the fact that it fragmented the way it did and that is is of a friable structure, further leads me to believe that I might be right. The huge Tunguska bolide, thought to be a comet, broke up, vaporizing, exploding miles above the ground most likely due to its friable structure.

Comets are not just ice as they are most commonly called "dirty snowballs" with dust and larger chunks of rocks inside. In fact, many asteroids that are being photographed close up show surface structure like a clustered pile of rocks, most likely the remnants of a earlier comet that has lost it's ice. In fact one supposed rocky asteroid was recently photographed with a faint tail, probably dust and residual ice evaporation into space.

Hi Steve & all,

I have the direction of Richardton coming from the SSW.?? I have a copy of the strewnfield map in my book "From Weston to Creston" (2016).?? The reference I got this from is from Murphy & Forsman (1998) Meteorites in North Dakota" in North Dakota Geol Survey Educ Series no 23, 23 pages. ??

All the best,

Frank

Steve,

Welcome back!?? Glad you are still involved.?? Has it been since 2003??? If I remember correctly it was a spider bite that sidelined
you.

Cheers,
