I like this because it means that even though we have all kinds of technology and social media, there are still wild places to find.We were self guided - 13 days on the water. We were dropped off near Rose Harbour, and our plan was to paddle back to Moresby Camp, preferably via the 'outside' route. We were able to complete our route as planned.
We had a pretty knowledgeable group, and we did a lot of leg work/research beforehand, but even so we were surprised at how often our proposed campsite either didn't exist or was completely unsuitable. There were sites that were probably fine at one time, but had been rendered uninhabitable by extensive blowdowns. Other sites that appeared in literature or on maps just didn't seem to exist. You can spend a lot of time bushwacking around a beach, trying to find something that isn't there. I think a lot of the literature out there is dated and hasn't aged particularly well.
Our best campsite intel came from conversations; we were put on to a couple of great sites through chance encounters with other paddlers. We also found a few hidden gems completely by chance. At the end of the day we always found something, but it can be a bit disconcerting when you pull in after a long day to a site advertised as 'large open site, room for 10+ tents", only to see a tangled wasteland of blowdowns and overgrown brush. Well, all part of the fun, I suppose!
Also, I recommend you take site descriptions on the BCMT map with a small block of salt -- unless you have a 1st hand scouting report or it is noted as updated by SCR or BCMT volunteers within 12 months. I state this having worked on the BCMT site database myself. "Site requires brushing" generally means with a chainsaw and small excavator.
I hope you turned in SCRs for your visits. It is only through diligent reporting by site users that any of that data gets updated.
