Hawaii, Part 7 (Big Island: Windward)
I’ve mentioned previously the difference between windward and leeward, and how it’s particularly pronounced on the “Big Island” of Hawaii. We used the windward side as our home base so we had our share of tropical moisture and verdant vegetation. It rained every day where we stayed south of Hilo. However, we never had what…

Hawaii, Part 5 (Big Island: Lava)
The “Big Island” remains the most volcanically active of the chain, perched directly above the Hawaiian hotspot.

Select African Superlatives
I thought I’d lump another set of somewhat related items together as I continued to cull the enormous backlog of possible Twelve Mile Circle topics. However, they didn’t have much in common except that they all involved continental Africa. Two involved geographical observations and the other two related to geological oddities. All of them piqued…
