Many people are fascinated by Alaska. They want to know as much about the state as possible. That's why there are so many different television shows that are about Alaska and adventuring in Alaska. If you are one of the people who are just dying to know more about Alaska, there are a lot of ways that you can do it.
One thing that you can do is to find memoirs of people who have explored Alaska. Memoirs are books that people have written about their particular journies through a place or during a time. For example, you may find one person has written several memoirs. Those memoirs may cover various time periods as well as different trips. That can make it easier for you to find something that is perfect for you to read. If, for example, you are into mountain climbing, you can look to see if a particular adventurer has a volume specifically on climbing the mountains in Alaska versus just exploring the wilderness.
In addition to memoirs, you may also want to look at biographies of people who have lived in and explored Alaska. The biggest difference between memoirs and biographies is who wrote them. A memoir is written by the person as a story of their memories and adventures while a biography is written by someone else about a person's life. Biographies tend to be more objective. That's because the author is going to have some distance from the subject of their book. Even if the person is still alive, the author is going to look at a lot of different sources to get information instead of just depending on the subject. For historical subjects, the author may also have to do a lot of research and talk to other researchers in order to get the best information possible about the subject. A biography can be a great way to get more obscure information that you might not otherwise have been able to find on your own because the author is going to have access to sources and research that you aren't going to be able to get to.
If you are interested in Alaska, there are a number of ways that you can get more information about people who have lived in Alaska, who helped to found the state, or who have explored Alaska. Reading memoirs and biographies are just two ways you can get that info. For more information, look into a person like Jzonay Reitz.
