Hi Linda, our High-Altitude Baking Guide has some suggestions for adjusting your bread baking, although increasing the baking temperature isn't one of them. One thing I've noticed from my moves across the country, is that baking in a different oven can also make for a challenging baking experience. For oven-related changes, I would begin by purchasing an inexpensive oven thermometer and preheating your oven for a full 30 minutes. If the temperature reading on the thermometer doesn't match up with your desired temperature, adjusting the oven dial accordingly and waiting for the thermometer to read the correct temperature may be helpful.
