Climbing registration is optional. There is a climbers
register in the WyEast day lodge foyer at Timberline on the South Side
of the mountain. No other trailheads have climbing registers, just self-issue
wilderness permits.
If you register please remember to return to record
that you are back ok. Many people don't do this and it makes it difficult
to tell if somebody is really on the mountain or whether they went
home.
Please be aware that the Forest Service does not always
check registrations on a regular basis. If you are late returning it
may not be discovered for several days. Early in the season (and even
during high season at times) weeks worth of registration forms have
been known to accumulate. Registering does not guarantee that anyone
will discover you are overdue, nor does it guarantee a rescue will be
initiated.
Unfortunately climbing registrations have reportedly been
the basis for privacy violations during rescue efforts. They have also
shown up in Forest Service investigation files on people they dislike
(whether they are for that person or for somebody suspected of having
even a tenuous connection to them). Given these facts and poor monitoring
of the forms it may be best to be sure that somebody you trust has all
pertinent information such as your planned route, list of equipment
and supplies, and time expected back as well as the amount of time your
group is prepared to be out for. Count on this person to initiate a
search/rescue effort directly with the county if necessary.
While a Mt Hood locator unit will help rescuers locate
a party in poor weather it will not summons help. In addition to leaving
your plans and preparations with a trusted party it is advised that
parties carry some communications such as a cell phone or VHF radio.
