Before striking out alone, it’s worth taking precautions against the following:
Temperatures (cold as well as hot) can be extreme in midsummer (May to September) and midwinter (January).
It’s easy to get disoriented amid the craggy peaks and maps are often inaccurate.
Passing traffic is rare.
Natural water supplies are not common and sometimes undrinkable.
Walking in sand is particularly exhausting.
