Nate, this is a great idea!

Here are some of my favorite and most useful resources (for a small practice)

If you aren't utilizing free GIS resources and LiDAR for project planning I strongly recommend it. Especially in rural areas getting into a site it helps to see an old flume or logging trail to try and travel along.

I have a few other free resources but they are county or region specific. There are a lot of free test prep resources out there too (and free books now available as the copyright expired).

What else do you guys use to get the job done well?

When I was still working, I used the NGS Data Explorer for "desktop recon" to look for control. I would use the street view feature to look for the mark, or evidence of the mark, after reading the description on the datasheet. I could also look for other features like GPS compatibility, safety of parking and set up, multi-path potential, etc. They have replaced it with the NGS Map (licensing issues with Google) which initially didn't have a street view function. Now that function can be accessed by clicking on a mark of interest, then click on Google Maps street view "more info".

I did recon of hundreds of control points along the Klamath River to assist the federal crews with locating control when they came out to perform bathymetric surveys prior to the dam removals on the Klamath. Not the same as "boots on the ground", but I was able to eliminate many, saving time, and find many others that were likely there and suitable for the project.
