Keep Your Outdoor Adventures Safe and Enjoyable! Natural Direction Indicators Lost your compass, watch, map, and GPS? Rather than being in a hopeless case, if you've got your wits (the most important survival tool) and some basic knowledge of the natural environment, chances are you'll be fine. Use these natural indicators of direction to help you re-find your way.
Snow stays longer and is usually deeper on north facing slopes. North facing slopes tend to be cooler and shadier because during the fall, winter and spring the sun is predominantly shining on the southern slopes while the northern slopes have little direct sunlight.
These two pictures show that the north sides of the slopes have conifers while the sunnier south slopes are covered in grassy vegetation.
Wind blown vegetation generally leans to the east. Weather systems, and the high altitude winds that move them, generally move from west to east. This happens because of a natural phenomenon called the Coriolis Effect and deals with the rotation of the earth.
Warning these are general tendencies, the local climate can alter them. Click below to learn about natural weather indicators

The
"aspect" ( the direction that a slope is facing)
has some determination on plant species and
their distribution.
Many
species of barrel cacti lean towards the south.
By leaning to the south the cacti has a minimum
of body surface exposed to the drying effect of
the sun.
