Ground Temperature measured during the summer
The high temperatures of summer can cause heat exhaustion or even heat stroke. Avoid strenuous activities during the day. Drink plenty of water, even when you are not thirsty; your body can lose large amounts of water without you realizing it.
Wildlife: Rattlesnakes, one type of scorpion, and the Gila monster are poisonous, but will leave you alone unless disturbed or cornered. Wear sturdy boots and watch where you step.
Amoeba: A microscopic amoeba, Naegleria fowleri, which can live in hot springs, can cause a rare infection and sometimes death. Do not dive or submerse your head in warm springs or associated streams.
Plants: Oleander is a toxic plant common to developed areas; neither you nor your pet should eat any plant part or drink water from ditches near the oleander.
