Hi, Lanny–
That capability to find placenames of unknown locality can be quite
significant to a mineral collector – I know from books that fluorescent talc,
tremolite, anthophyllite, and tirodite are mined in "Balmat, NY" and
"Talcville, NY", but cannot find their precise locations in my world atlas. Is
it near that Vermont talc belt mentioned here recently, I wonder? I suspect
DeLorme would give me an immediate answer without my having to order a map or
keep a great pile of state maps ("Oops, I must have taken out the NY map and
left it somewhere"), allowing me to order a topo map further in advance of a
trip thereabouts (with a wide collection of topos on CD, I could be ready
map-wise for a trip in minutes instead of days or weeks). And when I have a
placename without even a state on a specimen, a comprehensive E-map collection
would be so much easier to search.
When I went to seek ferrierite with Rod a couple of months ago, we went to the
new site and collected, and then tried to find the old site in the dark – the
construction was making trouble for Rod's memory, so I checked him by cranking
up my laptop and finding an old message from this forum in which he gave
directions to Nathan. Had it been paper, I would have left it in OK; this trip
was semi-improvised. We still did not find it, but at least we had a better
chance. With CDs and ever-larger hard disks, I should be able to bring whole
file cabinets of info with me anywhere I might go. Don't you ever wish you had
thought to bring a certain map with you somewhere? E-maps allow you to bring a
ton of maps with one decision. If I remember my laptop, I have remembered to
bring every E-document I have, more or less. But if I have it only on paper, I
must think of each individual piece of paper I might need, relying on my
fallible foresight in choosing them.
