Subject: RE: Zion, southern Utah, north rim of Grand Canyon. My MIL just came back from there, and she didn't mention the heat. I suppose it depends on what you're used to. She's from Redding, CA, where it starts getting HOT in May. Take lots of fluids with you. When we hiked Hetch Hetchy in June, it was in the upper 90s. We each carried 2 liters of sports drink with extra salt, and ran dry around the 6 hour mark. We had iodine tablets just in case we needed to refill with creek water. |
