My ranch was about 15 km east of New Hazelton and on the north side of and adjoining the Bulkley River. The Sitka Spruce trial was considered an interior trial and I have to say the annual growth was remarkable!! In an adjoining lot to the trial I had several hundred acres of massive old growth (Engelman?) spruce which I attempted to sell for Japanese export but they were not interested due to the huge annual growth rings like your uncles place. They wanted very large trees with very tight growth rings. I also had some massive Cottonwood trees that they did buy. The butt end of some were so big it took two 966 Cat loaders to put them on the logging truck, even though we cut the log lengths down to 30 ft which barely reached both bunks; one log per load. When we delivered them to Kitimat they had planned to take them off using a (huge) 980 Cat loader but no go. They had to bring in a Leuturno loader to do the job, and used their 980 loader to hold down my trailer, the logs were wedged so tight between the stakes.
Lots of Silverngold memories. :o)
