Beneath Robillard Mountain
Craigmont is about as distant from the reach of the modern world as you are likely to get in the “near north”. Indeed it appears on the map as a substantial settlement but as you cruise up Boulter road you become aware of how far you really are, both geographically and culturally from the bustle of Southern Ontario.
Coasting over hills that stretch off greenish-blue into the summer haze it seems as though you are crossing into a time warp. Meadows are saturated with intense colour and high pastoral fields line the road, strewn with orange and yellow flowers. Beyond this lies the valley of the “Little Mississippi River”. Spike-topped conifers wander unbroken to the horizon and in hillside fields lazy cows watch disinterestedly at the crumbling demise of old log barns.
As a collecting locale, Craigmont is remarkable. Not only is the beauty unsurpassed but its minerals are spectacular. Corundum here is found in large euhedral (perfectly formed) specimens; lapidaries have been known to cut them into cabochons. In their book, “Rocks and Minerals of Ontario” the Ontario Department of Mines say that there are unusual curved mica crystals. Garnets, molybdenite, allanite, uranite, euxenite, magnetite, pyrite and hornblende also appear from time to time.
Blink and you just might glide past Craigmont. The inhabited part is now a private town. It exists as a cluster of houses, barns and sheds and around it the vegetables flourish in earthy rows.
Robillard Mountain is situated within sight of the present habitation; an impressive upheaval of rugged red rock. Some twenty separate excavations scar its slopes.
As a general rule most corundum is found in pegmatites and structures associated with nepheline syenites. In this area north of Bancroft the most abundant deposits (corundum) are said to be sandwiched between scapolite, nepheline andesine and a band of alkaline syenite.
I took a hike beneath the mountain to see the syenite from below.

Well, Rockwatching has been up and running for a number of years now (5 to be exact) and I believe it has contributed significantly to the interest of people like myself who like caving, rocks, the outdoors, gems and minerals in Ontario.
We are just a few short days from 2011 and I believe it’s high time we made some resolutions -all of us (you my loyal fellow bloggers as well).
So in the interests of all involved a few ground rules to follow on Rockwatching from now on
1) Lets not carry a personal vendetta onto this site which is meant to be a forum where like minded enthusiasts can interact in a positive way.
2) Lets respect each other and try not to get personal when we are frustrated.
3) Lets respect the basics of conservation and eco-minded thought.
4) Lets not assume stuff we don’t know for sure (hence the survey at the bottom of the post).
5) Lets keep in mind that this is all about enjoyment.
6) Lets keep in mind that just because the topic is on the table, every single aspect that pertains to it is not an open book.
7) Lets respect people who are not on the site, private property, reputations etc. Just because there is discussion of a site or feature does not mean permission has been granted to go there.
8) Lets not get petty, self righteous or important. Stop correcting my grammar, spelling or use of terms. I am a writer at heart and so I believe I can use the language as I please (providing it’s in good taste, or if I choose, not in good taste).
9) Lets not waste my time by having to re-direct you to one of the above rules.
Happy and prosperous 2011 – Mick

finding sapphires in Ontario
I found the blackish crystal encased in calcite at the Faraday Hill road cut near Bancroft; only the tip was protruding from the rock and I roughly chipped it out and dissolved the calcite from it using Coca Cola.
The two rough reddish crystals are Mysore Rubies from India – not woth much at all and the cab is also from India, I bought it from Sahib for a couple of dollars – its way to opaque to be of much value but I liked the way it showed the zoning so clearly.
