Photo: McDowell Mountain Preserve

It will soon be hiking season in the Valley of the Sun, as temperatures cool.  This photo from the McDowell  Mountain Preserve in North Scottsdale shows how houses are creeping into the high desert.

Most of the McDowell Mountain Preserve is park land, so it will remain in its natural state.

This week we have photos of the wildlife and people of Tanzania posted on our Viva la Voyage travel photo site.
