Vancouver, British Columbia/Accessibility
This is a project to show the difficulty of geohashing in the Vancouver graticule.
 Access Bottlenecks
Doing this project showed me that aside from all the water, there are only a few ways to get anywhere in the graticule that isn't the city. It did cause me to learn about the ones that do exist.
 Three Roads
Outside the Vancouver area in the southeast corner, and Nanaimo on Vancouver Island, the whole graticule has three major roads. First, there's highway 99 that enters the graticule at Delta in the southeast corner and runs through Vancouver to Horseshoe Bay. Between Delta and Horseshoe Bay there are cities, so numerous smaller roads, but approaching Horseshoe Bay the land narrows to mountains and sea and the access reduces. Past Horseshoe Bay the highway continues but balances on the face of a cliff from there to where it leaves the graticule just north of Garibaldi in the northeast corner. Even getting access to the water is difficult there, because you can't get over the cliff.
Next, there's highway 101, similarly situated between the mountains and the sea, on the Sunshine Coast and connected to other highways only by ferry. Highway 101 does not give access to any of the land inland of the coast. The only way to get to it is by boat up the inlets.
And finally there's Highway 1/Highway 19 on Vancouver Island. The interior of the Island is also sparsely served.
 Choke Points
I found myself typing the same place names over and over again, realizing that they were the jumping off points to try to get to everything else. The biggest is Horseshoe Bay. You have to go through it to get anywhere to the north, either by the Squamish Highway, by ferry or by water taxi. Once on the Squamish Highway you have to leave your vehicle behind and cross the river by cable (not cable car, a cable strung between towers across the river) or boat. And then most of the mountains have glaciers and constitute technical climbs.
If you go from Horseshoe Bay to Langdale then your last point of civilization is either Earl's Cove or Tuwanek, and you have to kayak/hike the rest of the way.
Nanaimo is another ferry hub, allowing access to many, but not all of the islands.
Except as are very few secondary roads serving anything other than the immediate vicinity of the three highways. That's why we always seem to be going to Horseshoe Bay or Earl's Cove.
An area that didn't arise during the month, but is an important restriction is the watershed around the dams. Restricted.
 Explanation of Table Fields
All distances and times are one-way from Robyn's house, in roughly the middle of Vancouver. Routes are the most efficient Robyn can calculate, with possible alternates when there might be more than one way to approach a point. Driving times include ferry crossings and are from Google Maps. Cycling times allow 20 km/h, or as required by terrain. Walking allows 8 km/h on roads or good trails ranging down to 400 m in an hour in dense bush with poor footing, or less when climbing extremely steep terrain. Kayaking is 3 km/h, which accepts that we aren't very good at kayaking and includes an allowance for launching. Ferry times are not included in water distances, as they are in driving distances and are taken account of in total times.
From last, is the distance from the previous location, were I doing the endurance geohash. Such distance does not allow for getting to and from a safe place to camp between geohashes.
The times for the hikes are taken from bivouac.com. Many of them involve time-consuming mountaineering or circuitous routes that make it much further than the straight line distance shown. Some of these look to be only a few kilometres from access roads but experienced hikers at bivouac.com report them as multi-day hikes. In some cases I'm uncertain whether the terrain is that bad or the apparent access roads are unusable. -Robyn 18:08, 3 April 2009 (UTC)
The last column "Comment" is usually an excuse why I did not attempt/reach the geohash. It contains a link to the expedition if anyone went.
