Chumango, from what I recall about the trees listed, it had no relation to shape of tree. The study tried a couple correlations, with the only hint being water transportation (higher sap flow might correlate with more strikes). But it was not very well correlated. On the "cave" on Half Dome, it is more of a rock shelter than a cave, a slight overhanging roof. The perfect spark gap that gets a lot of people who think they are sheltering from the rain but don't realize that they are filling the gap for the lightning current.

Dave, don't count on any tent to stand up all that well in hail. Small sleet and grauple is probably ok, but when it gets to golf-ball-size or larger, it will go through almost anything. Whether a fly or single wall stands up better will depend on the material and age of the tent. Basically, don't count on a tent as a hail shelter or lightning shelter.
