On The Fly

I awoke to the steady patter of rain on my tent in the black velvet darkness of our cozy mountain camp. Wrapped in my sleeping bag, I sat up and listened, there it was again, some strange sound. Anxiously, I reached for my watch and clicked the Indiglo light. It was just after 1:00 a.m. and sleep eluded me. What was that sound? Was it a Bear? The skies were ominous that night. The steady rain began at dusk, we had retired early camped near Chickenfoot Lake , in the Inyo National Forest, elevation 10,789 feet, in the Sierra Mountains just northwest of Bishop, California. This was the second night of our annual wilderness backpacking trek. Our evening conversation always centered on BIG , ferocious bears. It wasn’t that long ago campers simply hung their food in trees. Not anymore, the bears had wised up to that old trick. Proper precaution requires every scrap of paper, food, trash, toothpaste - anything that has a smell gets packed into the bear proof canister for the nig...

Over the course of a career teaching gemology, students have asked me many questions that gemologists tend to take for granted. This hit home recently at a writers group meeting when I casually used the term refractive index in one of my fictional works and the question immediately came up, “What is refractive index?” This brief column is devoted to you, the curious student. It is an opportunity to ask anything you ever wanted to know about gemology (within reason) but were afraid to ask. So let’s begin. What does refractive index (R.I.) mean? Gem-A Refractometer The amount to which a gem slows light is called its refractive index (R.I.). R.I. is calculated by the ratio of the speed of light in air to its speed in a gem. It is one of the measurable properties that gemologists use to assist with a gemstone’s identification.  For example, using your smartphone or computer, go to the computational database WolframAlpha . Type in “What is the speed of light in air?...

Summer on my calendar has officially arrived. The fourth of July celebrations have already come and gone and Le Tour de France is underway! This morning the sun peeked over the horizon in California at 5:45 a.m., a comfortable 60 degrees, the skies were turquoise blue, the winds calm, bird’s singing quietly in the background, and the fresh smell of the trees filled the air. Well, not exactly, you see today’s chore was to empty and completely scrub the cats litter box. As you might imagine the smells were not exactly that of a floral bouquet. Anyway . . .  For me, summer continues to build the anticipation of this year’s annual high Sierra adventure. This will be my fourth consecutive year wildness backpacking near Bishop, CA. It’s less than two weeks away and my motivation for training increases daily as the trip approaches. My challenge is to not overdo it, maintain a balance between workout and proper rest. As a devoted cyclist and French compatriot, anticipation al...
