There's lots of fun stuff to do with RoseLine besides hiking to the top "because it's there"! The entries below suggest some interesting ways to explore your state, your mountains, and your surroundings that you might not have thought of. A few have detailed, easy to follow instructions that lead you through the process of answering the question. Some have pretty specific answers and others are difficult and left for you to explore. Some involve other tools - like spreadsheets. If you like puzzles you might skip the instructions and figure them out yourself. If you have a fun way to use RoseLine or a cool solution to one of the questions below, send a description to us (at ) and we'll add it here. 
 

	What are the names of all those peaks I can see from my living room window?
	What are the names of the peaks in that picture?
	Can I see my house from X?
	From which summits in Washington can I see the Space Needle?
	From which peaks in the I-90 corridor can I see the Space Needle?
	How to create a list of every peak in my state sorted by elevation? Wow! I just figured out that Mount Si is the 2000th highest peak in Washington !
	If that big peak isn't Mount Olympus (then which one is!?) and where can I go to see it?
	Which peaks in Oregon are NOT visible from the summit of Mount Hood?
	How to make a list of peaks in Washington from which I can see Mount Rainier?
	From where in Oregon can I see Mount Shasta (in California)?
	How high do you have to go in order to be able to see every peak in the state?
	Which islands in the San Juans am I seeing?
	What is that "thing" blocking my view of summit X?

Haven't you wondered what are all those peaks you can see from your living room window, friend's magnificent office view, your favorite park, that bend in the road... OK. This is pretty straight forward.

	Get the latitude and longitude for your home - here's a cool web site (http://geocoder.us/) that will convert a street address to latitude and longitude. If that doesn't work for you, see here.
	Start the RoseLine program on your local computer
	Create a custom viewpoint for your home.  see instructions here.
	Type the name of your new custom viewpoint in the box labeled "enter viewpoint" and press "Show names of visible summits".
	Now click the "Reset Filters" button just so we start with the filters in a known configuration.
	Set the Heading filter to match the direction you're looking and estimate the field of view You need to know what direction (in degrees) you are looking from your viewpoint (living room window) e.g. due East is 90. We'll estimate that your field of view is about 60 degrees (30 degrees either side of due east is a range of 60 - 120 degrees) but you can experiment with this. make sure the checkbox "Enable" under "Heading Filter" is checked. We'll set the heading filter according to our example above but use your own numbers. Set the Heading Filter range to say "60 clockwise to 120" by clicking the little up/down arrows. (hint: you can hold down the arrow)
	The Visible Targets list now contains the 40 most prominent peaks as seen from your viewpoint.
	The list is sorted alphabetically but if you click on the header labeled "Heading" in the Visible Targets list it will sort them clockwise according to the compass - or left to right across your living room window.

Have you ever wondered just what is the pass/gap/mountain/lump/THING? that is blocking what it is you're looking at? If you have National Geographic TOPO installed you can find out.

	Create a RoseLine map for TOPO that includes your viewpoint and the mostly obscured target.
	In TOPO, make sure you have the "route tool" selected and right click on the Rose Line from your viewpoint to the mostly obscured target.
	Select "Build Profile"
	On the TOPO map, navigate to level 5 (ie. zoom in to the maximum)
	Now on the profile you just built you can kind of draw a mental line-of-sight from your viewpoint (on the left) to the target (on the right). As you move the mouse cursor over the profile you'll see the yellow cross-hairs match your movement.
	Some where between the viewpoint and the target there will be a place where the profile jumps up and almost touches your mental line-of-sight. click on that spot and the TOPO map will automatically navigate to the corresponding place. You should now be able to see on the map the ridge/gap/mountain or whatever that was blocking the view at that spot.

Hmmm. I thought this was easy at first but then... it got more complicated

	OK. Create a custom viewpoint (see how here) that is approximately in the middle of your state and 2500000 feet high.
	Yes...  that's 50 miles.
	Then select that high viewpoint and press "Show names of visible summits" to calculate what peaks are visible.
	Press "Reset Filters" just so the filters are in a known state
	Uncheck the checkbox labeled "Limit display to nn best peaks" (in the upper right)
	Check "binoculars" (lower right)
	The Visible Targets list now contains ALL the peaks in the state.
	You can now sort the Visible Target list and peruse the data.
	Choose "Output format" of text and press generate to see the list in notepad. You could also select the CSV output format and look at the list in a spreadsheet.

Ok, so there's a couple problems with this. First, the list of peaks also includes lots of peaks in the neighboring states. You'll need to remove them by sorting on the "Region" column (in RoseLine or in your spreadsheet) and eventually deleting the entries you don't want.

And actually the list only contains the mountains with elevations greater than 3500 feet...

Note that the list also contains "custom viewpoints" which can be recognized by the fact that they have "User" in the "region" column of the Visible Targets list.  Remove them as described above with judicious sorting and deleting.

Once you have the list in a spreadsheet it's pretty easy to sort on the elevation column and then find the Mount Si (in Washington) is the 2000th highest peak in the state.
