Is it safe to look for meteorites in deserts?
Only with careful planning. Deserts bring heat, dehydration, getting lost and vehicle breakdowns, and some regions have security risks and legal restrictions.
Deserts are among the best places to find meteorites, but they can be dangerous. Anyone planning a desert search should prepare carefully.
Heat and sun. Daytime temperatures can exceed 40 °C. Heat exhaustion and heatstroke are serious risks. Search in cooler seasons, early in the morning or late in the afternoon, wear a hat, light-coloured clothing and sunscreen, and rest in shade.
Water. Carry far more water than you think you need, at least several litres per person per day, plus spare supplies in vehicles. Dehydration can happen quickly in dry air.
Navigation. It is easy to get lost in featureless terrain. Use GPS devices with spare batteries, carry maps, and tell someone your route and expected return time. Satellite communicators allow emergency messages where mobile phones do not work.
Vehicles. Use reliable vehicles, travel in pairs where possible, and carry spare tyres, tools, fuel and recovery equipment.
Wildlife. Be aware of venomous snakes, scorpions and insects. Check shoes and equipment.
Weather. Sandstorms reduce visibility, and flash floods can occur after sudden rain, even in dry riverbeds.
Security. Some desert regions have security risks. Check official travel advice before going.
Law. Many desert countries regulate or ban meteorite collection and export. Get permits and follow the law.
Group work. Search with experienced people and never alone.
With good preparation, desert searches can be safe and rewarding, but they are not to be undertaken lightly.
