    Does anyone have a map of named runs on the Paralyser? Yeah I know side country not back country. But you gotta do BC things to get out and back.

    I have some runs named but can only express them as waypoints for the starts, after the start follow the fall line.

    Can crayolla man @VSG show them on a map?

    Thats World Grid Sytem 1984 (i think) and its about as close to as you can get on a GPS.

    Why wouldn't you use WGS84?

    For practical purposes WGS84 = GDA94.

    For what it's worth the paper maps are GDA94.

    Either in gps or with brilliant map & compass work will get you within the 5m circle of startruness.

    Because mga94 is the australian grid until it is replaced with the new one mga16? Dont know where skifree plucked numbers but if it was an australian mapping site or a newish topo it will be mga94.

    There are 4 datums you might have australian maps using. These being wgs84 gda94 agd66 agd84. All of those datums dont differ by more then about 200m and the first 2 are the most likely you will come across on a recent map or using a gps and are within a couple of metres of each other. So its generally safe to ignore th datum.

    The other issue is the projection. The first option is unprojected coordinated ie latitude and longitude. If you use these you need to use 4 or more decimal places to be within 10m. Some might use degrees minutes and seconds in which case you need to go to the nearest second to be within 30m.

    Next option is a projected coordinate system. There are many but the ones used on topo maps are all UTM based. MGA and AMG are just UTM projections for particular datums. UTM coordinates are in metres east and north of the UTM zone origin. You need to use all the digits and also a zone number.

    So if the sh!t hits the fan ive given you 3 ways to quote coordinates and confuse the rescuers. Given enough time they will work any of them out but my understanding is lat and long as decimal degrees is what they understand best. Its what the official emergency app uses.

    Also give a description of your location. It will stop them searching in the wrong spot if they transcribe the coordinates wrong.

    I was reminded about this yesterday during some skinning natter. So after a bit of a break I might get back onto this little project.

    Some more points that folks would have heard me talk about.

    PN-Silk Bowl 55 H 622683 5972094, the bowl visible from the Log and Bloody Mary.

    PN-3 Way Cross 55 H 622947 5972371, the place the cross the creek below the Log after dropping either Silk Bowl or 3 Way Spur.

    Yes all coords are UTM GDA94. :rolleyes:

    @Richard

    I’ve just noticed iPhone turns the coords into phone links. Is there any way the wizzy forum software can turn into click coords that take you to maps?

    Just to complicate matters GDA2020 is in the process of being rolled out, but I would guess that it will be a while yet before it replaces 94 as the go to for most. For those using GPS, WGS84 is generally the is most widely used and likely the best bet for those trying to find you with navigation tools, GDA1994 I am sure would be fine as well.

    I've since done it twice, both times on the pre-splitfest Friday arriving at Guthega around noon and the long skin up the valley, 1 big run and the cruisy run back down the creek to Guthega. I reckon when I drop Paralyser I'm doing at least 2 if not 3 skier runs in 1 run :)

    Snowcat. Loops continuously around Paralyser summit ridge and Spencers Creek valley below, going just high enough on Mt Ps west side to traverse back in to Eyre with a quick side dash up Kosci Rd to allow a traverse back into Guthries at Charlottes for return to resorts. $5 per uplift.

    Cos I can.

    And it helps when I’m talking locations with people. Just a handy thing.
