Hello Klif01 -
The two you cited in the Moab area... Tipover challenge on HRv, and the Wedgie on PSm are both legal routes and are marked.
In fact although right from the get-go (as long as I've been here) Tipover was always used as was the wedgie, the RR4W have a guiding principle which is that when a RR4W Trail leader is leading a group, one should always exercise care in selecting the route to be used. Without getting too much into detail, it has often be suggested to not take the harder route, thereby avoiding the "egging-on" of participants to follow suit.
It should also be noted that Kenny's Climb on the Fins and Things trail was never marked, although that route has been used since the very first day that trail was created. The actual route is marked and does a jughandle loop which bypasses Kenny's climb.
Lastly, it is the principle of RR4W to (generally) refer to any other route used which might be considered to be the easier, less hazardous route as the "alternate route" and not usually as a bypass. There are exceptions to that general rule. It has also been said that on some trails where the hazard level would be marginally higher, that the more traditionally used 'challenging' section itself be called the alternate route. I've never found that any steadfast terminology for the given instances and examples was absolutely and ultimately arrived at. Anyway, that is basic trivia on the overall scope.
However, I hope I've helped to address your post to some degree of satisfaction.
Regards,
Capt. Picky
