Dear World -
You may close with "Grace and Peace" but I still consider your insistence on cycling through the Mojave to be more than foolish. And I also think that you have received some pooor advice in this thread.
Here's what I know about you and your plans:
1) You are a novice cycle tourer.
"..so I had this crazy idea (that must be how all first-time bike tours start) "
2) You are not aware of the geography or the climate of the Mojave.
Is there anything I can do to minimize the heat factor for that first week or so? I was thinking of getting up before dawn and riding from say, 4am - 9am... and then pitching my tent (shade), and doing another push from 4pm to 7pm or so. I would hopefully avoid riding in the most intense heat this way. This is just an idea... has anyone tried doing this before?
3) Your "research" is Google Maps.
I'm a little concerned about the 'routes' that Google maps provides. A lot of them seem to be quite a bit from the main road (which doesn't seem very safe to me). What is the best way to plan a route like this (where there is no ACA maps?)
The person who said this doesn't apparently know the Mojave:
I wouldn't worry too much about the heat. Deserts always cool down plenty at night. I have bicycle toured in 45 states and the hottest place I've been was Interior in the Badlands of South Dakota - 114 degrees. I just made it a short day. You can hit hot weather anytime, anywhere in the summer. Weather fronts are always rolling through and changing the temperatures and wind direction.
The average highs for Barstow and Needles in late July are 103 & 109.
The record highs for Barstow and Needles in late July are 115 & 120.
The average lows for Barstow and Needles in late July are only 70 & 85.
On warm nights it may not get below 80 near Barstow and 90 near Needles.
It ain't like South Dakota.
And it isn't like central Nevada, either.
For ex - Middlegate has an average high in late July of about 93 and low of 51.
The heat, heat index, and humidity are a geometric factor more severe in the Mojave.
You've never done this before.
It's all in your imagination.
Trust me - the reality is intense.
