Access Map

I have updated the current news, information and access map for two things. First, I converted all the locations to WGS84 latitude and longitude so they will plot better on Google Map. Google uses WGS84 instead of NAD83 which are slightly, but not significantly, different locations, when you zoom in on places on the map.

The second is that I've added 8 new places and relocated some of the places for better representation on the map. The new places are mostly in the Longmire, Paradise and Sunrise areas to provide more information of the facilities and activities there.

I've also updated the information from the NPS schedule for winter closures or reduce days and/or hours at facilities and campgrounds. All the roads are currently open and will remain until the NPS begins closing them on schedule or with the first significant snowfall.

I'll update the information again when we get into October and the actual closures have happened, often at Sunrise, or will happen in October as outlined in the schedule. The closures usually align with the Columbus Day holiday, the last good weekend and holiday in the NP.

Horizontal Datum

I've been reviewing the map with the current news, information and access and discovered when you zoom in on specific places, the points I have for Google Map, which uses NAD83 latitude and longitude, plot differently on Google Map than for the map applications I use for locating places.

This is because Google uses WGS84 and not NAD83. This is due to the fact Google needs a consistent world horizontal datum and not one specific to North America which I've used throughout my career with the USGS and with the maps for the Mt Rainier photo guide.

The difference can be small, almost insigificant, or obviously close but not right. So, I'll be adjusting the map for the news to WGS84 and checking the locations with Google Map. If this works to correctly plot the locations, then I'll work through all the maps to correct them to WGS84, but that will take some time.

In the meantime the difference is small enough to still identify what the point is and where it is in Mt Rainier NP. But for the information on the maps for elevation, they will still be NGVD 1927 and not NAVD 1988. The USGS still uses NGVD 1927 for a lot of application, reports and uses, so that's still the standard I'll use on the maps with the photo guide.

If you have problems with the elevation, all computer and mobile device map applications have toggles to switch between the two vertical datums, so it's easy to translate between them for your needs or work. As they say, if anything changes, I'll keep you posted.

Photography Places

Recently travel photographer Greg Vaughn published Photographing Washington of which a chapter is dedicated to Mt. Rainier National Park. I have reduced the information in the chapter to Web pages, Photography Places in Mt Rainier NP along with a map of the places in the book with a few variations.

While the book is an excellent resource for photographers visiting Mt. Rainier for many of the best places to photograph, it's doesn't present all of the places as the many are in the backcountry far from the visitor areas and locations and far off the roads requiring long day hikes or multiple day backcountry hikes.

That said, I highly recommend the book if you already photograph places in Washington state or plan to visit to photograph places in Washington state, and the chapter on Mt Rainier is the best presentation I've seen to date.

It encompasses many of the most and often photographed places in the NP and some of the lesser known or visited places. It opens the door to what other photographers will tell you, some of the best places are in the backcountry, where over 90% of the NP is open to photographers away from the tourist and photographers.

And this is good won't get old or out of date for information, the NP is always there waiting for you.

Camp Muir


This is the view south from Camp Muir (NPS Webcam) with, left to right, Mount Adams, Mount Hood (center in the distance), and Mount St Helens. The view looks down the Muir snowfield between the Paradise (east) and Nisqually (west) glaciers.

Camp Muir is a long day hike to and back down for some but mostly the stopover site for summit climbs where the climbers stay for the evening to arise in the early morning hours for the climb to the summit and back down to Camp Muir and Paradise.

Sorry about that

I screwed up and didn't upload the new table of contents with the changes for September-October news, conditions and access links. It's fixed. I apologize for the oversight. Too much work and too many other things in life I overlooked all the pages to upload.

I'll be updating them again in about a week or so when the NPS release its initial schedule for the reduction in days and hours and closures for the facilities, campgrounds, services, roads, entrances, etc. Those come out with the fall Tahoma newsletter which comes out after the Labor Day holiday.

I'll get the newsletter and update the Web pages with the specific dates and information.
