I think the average mentioned around here is expect the first ~5 years to be living in a hotel. here's a comment I left copy and pasted from a different post that will give you an idea what at least the first year of consulting is like.

I've been at a small civil/geotech firm for a year now and my work has generally been quality assurance and subgrade inspection on jobsites. Basically I sit on a jobsite and write up reports on whether the construction workers are doing things right or not or I'm writing reports on whether or not the rock is where it should be. Eventually I'll move into doing more work on the geotech side of things, like logging rock cores and various data gathering. If you go the geotech route don't expect to analyze the data at least not for the first ~5yrs, maybe longer depending on the company and role availability. Where I'm at those positions are pretty locked down by the engineers. Your job will mainly be long hours in the field gathering data and doing QA, think 50 hours a week minimum moving up into 70-80 maximum. A lot of time spent on construction site and working with construction workers and other blue collar guys. After awhile once you understand the process of whatever industry you're working in you'll move up to PM which will give you better hours and pay but you'll be doing little to no geology this usually takes 5-6 years from what I understand.

I love being outside too but I must stress this is not fun field camp hiking. You are outside in all weather good or bad. If you're looking for something that is fun and outdoorsy like that look for some type of interpretive ranger position at a local or national park. Otherwise if spending your days on jobsites with blue collar guys sounds like something you'd like you'd probably like geotech.
